Subject: 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.
