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

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=08e786536ba2b81d13e5b8319767c9b34f817f9a
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
