Khem Raj b7e6a763f6 perf: Pass LDSHARED and CCLD via EXTRA_OEMAKE 
python code underneath is smart and pokes at python installation in
sysroot for compile environment, the overrides from EXTRA_OEMAKE are
ofcourse preferred but it falls back to python3's distutils/sysconfig
for rest of them, and it does use CCLD and LDSHARED for linking, when we
use clang to compile python3 then it encodes these variables to be clang
however, when building perf we inherit kernel which forces gcc to be
used for compiling perf, which then mixes both compilers due to CCLD and
LDSHARED demands. Therefore override CCLD and LDSHARED in make
environment helps python/distutils to use right linker

subsystem that provide a framework for all things \
performance analysis. It covers hardware level \
