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.
