Adding some folks to the CC list, that either worked on the make
infrastructure or that I know works with cross compiling environments,
maybe they can help.

Yeah, we're really bad at documenting things, lemme try finding what can
help here:
tools/build/Documentation/Build.txt
tools/perf/Documentation/Build.txt
And in your output dir (O= or in place, in tools/perf/)
[acme@jouet linux]$ ls -la /tmp/build/perf/feature/*.output | tail
-rw-rw-r--. 1 acme acme 0 Jun 16 18:36 /tmp/build/perf/feature/test-libunwind.make.output
-rw-rw-r--. 1 acme acme 0 Jun 16 18:36 /tmp/build/perf/feature/test-libunwind-x86_64.make.output

[acme@jouet linux]$
So, a zero sized file means that feature was detected without a problem, lets
see one that has content:
[acme@jouet linux]$ cat /tmp/build/perf/feature/test-libunwind-x86.make.output
test-libunwind-x86.c:1:27: fatal error: libunwind-x86.h: No such file or directory
compilation terminated.
