Subject: perf tools: Emit more precise message for missing glibc static library
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9ca2d8918979e8ef806a8b6b4635a79b4f40d1a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
