Started getting Undefined symbols for architecture i386 "_getline"

[Woofbeans]

I've previously been able to successfully build the Lollipop AOSP (for hammerhead) but now for some reason I've started getting this error message and don't know how/where to fix it

Undefined symbols for architecture i386:

  "_getline", referenced from:

      _write_numa_topology in libperf.a(header.o)

      _write_cpu_topology in libperf.a(header.o)

      _write_total_mem in libperf.a(header.o)

      _write_cpudesc in libperf.a(header.o)

      _copyfile in libperf.a(util.o)

      _hist_entry__srcline_snprintf in libperf.a(sort.o)

      _machine__create_kernel_maps in libperf.a(machine.o)

      ...

ld: symbol(s) not found for architecture i386

Those look like kernel symbols from the tools/perf subdirectory of kernel.

This android-building group is more about building the Android platform, not kernel.

Try android-kernel group?

It is the Android Platform I am building, not the Kernel.
