linker is segfaulting after printing bunch of unresolved symbols
collect2: fatal error: ld terminated with signal 11 [Segmentation fault]
So it could be that your system is running out of memory, or perhaps a
linker bug.
it seems you are trying to natively compile llvm on a rv64 machine,
how much RAM do you have on this machine ?

This error
/usr/lib/gcc/riscv64-unknown-linux-gnu/7.3.1/../../../../riscv64-unknown-linux-gnu/bin/ld: /usr/lib/libcurses.a(lib_cur_term.o): relocation R_RISCV_HI20 against `ospeed' can not be used when making a shared object; recompile with -fPIC
means that you need to build a libcurses.so.
There may also be other problems here like the out-of-memory issue Khem mentioned. I know from my unmatched/Open Embedded work that we need about 12GB of virtual memory in order to build LLVM. And reducing the parallelism helps so that you aren't doing multiple links at the same time. You can just keep restarting the build after it crashes with less parallelism until it succeeds. If you don't have enough memory, but have disk space, you can just add some large swap files. It will be slow but should work.
Building LLVM stresses the whole system. If you are still using old unpatched versions of stuff you might run into toolchain bugs that we have already fixed. Looks like you still have gcc 7.3.1 which is very old.

I managed to build LLVM 13 on a Raspberry Pi 4 with only 4 GB of RAM, running RPi OS 32-bit.

Maybe it depends on how LLVM is configured, or what optimization options are used for the build. I'm not an LLVM expert; I just know what the SiFive OE LLVM build needs last time I tried it.

The resources required to build LLVM differ a lot between the release and debug builds, more so than most software. There's a bunch of info on the internet.

I don't know how RVV is implemented in LLVM, but in GCC it required quite a lot of memory; this might be another explanation for the linker crash.

I am running RISC-V Linux Image on QEMU, I have given a 25G RAM size. Can I try with 50G or its sufficient? and also I am using parallelism ninja -j8, is this the reason ?.

You can try but the memory available to QEMU will obviously be constrained by the actual amount of memory on the physical host machine.

-j8 should be just about ok with 50 GB. With only 25 GB limit it to -j4 at most.
You only have to limit the number of simultaneous link jobs, not everything. cmake has a flag for that.

As you suggested, I have installed libncurses. After installing the ncurses package also I am getting the error like this.

There are many things that could be going wrong here. You have the binary, and you have the sepc and other registers dumped, so you can try using a debugger to try to figure out exactly where and why it failed. The sepc is a high address not in the executable, suggesting that this might be a problem with a library such as glibc. If you have an old glibc, maybe this is a glibc bug that was fixed a few years ago.
You should also check for OOM killer problems, e.g. out-of-memory failures. If there was one, it should be mentioned in a system log file, exactly where probably depends on whether you use systemd or not. Or alternatively you can run top or similar in one window while doing the LLVM build in another window and watch the memory usage.
Or this could be a cascading failure. It makes sense to fix the easy problems first, and then come back to this one if it still is failing.
/usr/lib/gcc/riscv64-unknown-linux-gnu/7.3.1/../../../../riscv64-unknown-linux-gnu/bin/ld: /usr/lib/libcurses.a(lib_cur_term.o): relocation R_RISCV_HI20 against `ospeed' can not be used when making a shared object; recompile with -fPIC
Like before, this message indicates that you need a libcurses.so file instead of libcurses.a. Since it is using the full path, maybe this was written into a configuration file somewhere, and you need to rerun the configuration step to tell it that there is now a libncurses.so it should use instead.

Since only versioned symbols are failing here, this might be a glibc versioning problem, e.g. if you have more than one version of glibc on the system, and something was compiled with the new version, and you tried to link with the old version, then it will fail like this because the old glibc version won't have the symbols required by the new glibc solution. The solution is to link with the new glibc version instead of the old one. Otherwise, if you don't have multiple glibc versions, then this could be some kind of cascading failure. Or it could be an obscure bug somewhere, but try fixing simple stuff first.
