perf tools: Let python use correct gcc for build_ext
Currently, python uses host gcc instead of cross-compile gcc in the last
step of compiling build_ext(remove '--quiet' to show verbose):
cross-gcc ...
cross-gcc ...
creating ~/out/python_ext_build/lib
gcc -pthread -shared -Wl,-z ...
This is wrong but may not cause any errors unless the features detected
by cross-compiler do not match those for host compiler, and causes the
following errors:
/usr/lib64/gcc/bin/ld: cannot find -lunwind-x86
collect2: error: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
cp: cannot stat ‘~/out/python_ext_build/lib/perf.so’: No such file or directory
Makefile.perf:257: recipe for target '~/out/python/perf.so' failed
make[1]: *** [~/out/python/perf.so] Error 1
Makefile:68: recipe for target 'all' failed
make: *** [all] Error 2
This issue is also reported and anwsered on stackoverflow.
