Subject: tools/build: fixdep versus tools/lib/bpf

Hi Jiri, Wang,

	I'm getting these while doing 'make -C tools/perf build-test':

  LD       fixdep-in.o
  LINK     fixdep
/bin/sh: /home/acme/git/linux/tools/build/fixdep: Permission denied
make[6]: *** [bpf.o] Error 1
make[5]: *** [libbpf-in.o] Error 2
make[4]: *** [/home/acme/git/linux/tools/lib/bpf/libbpf.a] Error 2
make[4]: *** Waiting for unfinished jobs....


It happens at different tests, i.e. seems like a race somewhere in the
build system, can you take a look? It happens with my perf/ebpf branch.
