Tiezhu Yang 6a1515c962 perf build: Fix error message when asking for -fsanitize=address without required libraries 
When build perf with ASan or UBSan, if libasan or libubsan can not find,
the feature-glibc is 0 and there exists the following error log which is
wrong, because we can find gnu/libc-version.h in /usr/include,
glibc-devel is also installed.

  [yangtiezhu@linux perf]$ make DEBUG=1 EXTRA_CFLAGS='-fno-omit-frame-pointer -fsanitize=address'

After install libasan and libubsan, the feature-glibc is 1 and the build
process is success, so the cause is related with libasan or libubsan, we
should check them and print an error log to reflect the reality.
