[PATCH 5/5] perf build: Add make check-headers target

[Namhyung Kim <namhyung@kernel.org>]

Don't print header differences during the perf build as it's noisy.
Mostly people won't care and find it annoying.

As it's to improve perf trace beautifier to catch up new changes mostly
in UAPIs, we can make it a separate build target and call it
occasionally.
