perf tools: Add EXCLUDE_EXTLIBS and EXTRA_PERFLIBS to makefile
The goal is to allow users to override linking of libraries that
were automatically added to PERFLIBS.
EXCLUDE_EXTLIBS contains linker flags to be removed from LIBS
while EXTRA_PERFLIBS contains linker flags to be added.
My use case is to force certain library to be build statically,
e.g. for libelf:
EXCLUDE_EXTLIBS=-lelf EXTRA_PERFLIBS=path/libelf.a
