Tuomas Tynkkynen 710c4c3c9d linuxPackages_*.perf: Fix build after kernel 4.1
In 4.1, the build system changed, and it now wants to execute ld like this:

ld -r -o util/scripting-engines/libperf-in.o util/scripting-engines/trace-event-perl.o util/scripting-engines/trace-event-python.o

The actual problem seems to be that `buildInputs = [elfutils ...]`
causes 'ld' to point to elfutils in PATH instead of the usual binutils.

So remove elfutils from buildInputs and set NIX_CFLAGS_* manually. This
is a slight hack, but there is some precedent:
0761f81da7/pkgs/tools/package-management/rpm/default.nix (L13)

Fixes #9095.
