perf build: Don't fail fast path feature detection when binutils-devel is not available

This is one more remnant of the BUILD_NONDISTRO series to make building
with binutils-devel opt-in due to license incompatibility.

In this case just the references at link time were still in place, which
make building the test-all.bin file fail, which wasn't detected before
probably because the last test was done with binutils-devel available,
doh.

Now:

  $ rpm -q binutils-devel
  package binutils-devel is not installed
  $ file /tmp/build/perf-tools/feature/test-all.bin
  /tmp/build/perf-tools/feature/test-all.bin: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
  dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2,
  BuildID[sha1]=4b5388a346b51f1b993f0b0dbd49f4570769b03c, for GNU/Linux 3.2.0, not stripped
