I think this is objectively worse than just removing the file. It is
likely the perf tool can build with clang/LLVM, I do it every day, and
the special case for Android is likely more about the libc (aka
bionic) which gradually over time has been becoming more full fat -
perhaps we need to carry somethings in tools/include for missing
definitions, but we build with musl and that's a PITA in this regard,
we've also been reducing the tools/include dependencies for perf trace
beauty support. We don't use ifuncs in the perf tool (Android's
linker/loader historically hasn't supported these) and the weak symbol
games should be okay and something I aspire to make less in the perf
tool over time. As Android uses Linux then it should work and should
be supported.

Thanks,
Ian
