perf tools: Emit more precise message for missing glibc static library
When the user does: make -C tools/perf LDFLAGS=-static asking for a static build, and the glibc-static (or equivalent) is not found, the message wasn't clear, stating that one of glibc-devel or glibc-static wasn't installed, clarify it checking if -static is present in LDFLAGS.
