Cross-platform build failed on mips64el

[Madao Chan]

Greetings,

I'm trying to cross-platform compile 89.0.4389.130 mips64el build on a x86 Ubuntu 20.04.3.

Before this I've successfully finished the arm64 build.

After I downloaded the sysroot. I edited the args.gn:

target_cpu = "mips64el"
is_component_build = false
is_debug = false
enable_nacl = false
enable_linux_installer = true

But it got some errors in checking the args:

zf@zf-QiTianM435-B442:~/zf-browser/chromium/src$ gn args out/zf-browser-mips

Waiting for editor on "/home/zf/zf-browser/chromium/src/out/zf-browser-mips/args.gn"...

ERROR at //third_party/pdfium/third_party/BUILD.gn:485:43: Undefined identifier
  } else if (current_cpu == "mips64el" && mips_use_msa) {
                                          ^-----------
See //third_party/pdfium/samples/BUILD.gn:55:5: which caused the file to be included.
    "../third_party:pdfium_base",

    ^---------------------------

After I removed the "mips_use_msa" condition, I got this error:

zf@zf-QiTianM435-B442:~/zf-browser/chromium/src$ gn args out/zf-browser-mips
Waiting for editor on "/home/zf/zf-browser/chromium/src/out/zf-browser-mips/args.gn"...

^-----
See //ui/accessibility/BUILD.gn:294:20: which caused the file to be included.
      configs += [ "//build/config/linux/atk" ]

                   ^-------------------------

Then I removed the "current_toolchain" assert and ran the checks again. which is success:

zf@zf-QiTianM435-B442:~/zf-browser/chromium/src$ gn args out/zf-browser-mips
Waiting for editor on "/home/zf/zf-browser/chromium/src/out/zf-browser-mips/args.gn"...

Done. Made 19309 targets from 2655 files in 5877ms

But when I triggered the build, It came out with the following error:

zf@zf-QiTianM435-B442:~/zf-browser/chromium/src$ ninja -C out/zf-browser-mips
ninja: Entering directory `out/zf-browser-mips'

ninja: error: '../../third_party/pdfium/third_party/mips/filter_msa_intrinsics.c', needed by 'obj/third_party/pdfium/third_party/fx_lpng/filter_msa_intrinsics.o', missing and no known rule to make it

Which phase did I do wrong? Thanks.
