He Kuang 48d8d5db4a 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.
