perf build: Clarify open-coded header version warning message
In this patch we changed the header checks:
perf build: Clarify header version warning message
Unfortunately the header checks were copied to various places and thus the message got
out of sync. Fix some of them here.
Note that there's still old, misleading messages remaining in:
tools/objtool/Makefile: || echo "warning: objtool: x86 instruction decoder differs from kernel" >&2 )) || true
tools/objtool/Makefile: || echo "warning: objtool: orc_types.h differs from kernel" >&2 )) || true
here objtool copied the perf message, plus:
tools/perf/util/intel-pt-decoder/Build: || echo "Warning: Intel PT: x86 instruction decoder differs from kernel" >&2 )) || true
here the PT code regressed over the original message and only emits a vague warning
instead of specific file names...
All of this should be consolidated into tools/Build/ and used in a consistent
manner.
