[Buildroot] [PATCH] package/perf: fix build failures with high 'make -j' values

The 'perf' Makefile is flaky on some kernel versions. It will still parallelize
the build even with 'make -j1' because it explicitly invokes a sub-make with
the correct flags. But the top-level make is not smart enough to handle large
'-j' values.

# The call to backtrace() function fails for ARC, because for some
# reason the unwinder from libgcc returns early. Thus the usage of
# backtrace() should be disabled in perf explicitly: at build time
