Adding support to remove options from final CFLAGS
for both object file and build target. It's now
possible to remove CFLAGS options like:
CFLAGS_REMOVE_krava.o += -Wstrict-prototypes

That is cool, and I just looked and this comes from the kernel sources,
is there some place where the subset of such features that is supported
in tools/build is being documented?
Applying it, thanks.

Duh, yeah:

Nevermind, I'll add a note to the cset log.

tools build: Add CFLAGS_REMOVE_* support
Adding support to remove options from final CFLAGS for both object file
and build target. It's now possible to remove CFLAGS options like:
CFLAGS_REMOVE_krava.o += -Wstrict-prototypes
Committer notes:
This comes from the kernel's kbuild infrastructure, the subset that is
supported in tools/ is being documented at tools/build/Documentation/Build.txt.

Adding support to detect jvmti support. It is not plugged
into the FEATURE_TESTS machinery, because it's quite rare
and will be used separately from perf via feature_check
call.

Compile jvmti agent as part of the perf build. The agent
library is called libperf-jvmti.so and is installed in
default place together with other files:
$ make libperf-jvmti.so
BUILD: Doing 'make -j4' parallel build
...
CC jvmti/libjvmti.o
CC jvmti/jvmti_agent.o
LD jvmti/jvmti-in.o
LINK libperf-jvmti.so
$ make DESTDIR=/tmp/krava/ install-bin
...
$ find /tmp/krava/ | grep libperf
/tmp/krava/lib64/libperf-jvmti.so
/tmp/krava/lib64/libperf-gtk.so

perf jvmti: Plug compilation into perf build
Compile jvmti agent as part of the perf build. The agent library is
called libperf-jvmti.so and is installed in default place together with
other files:
$ make libperf-jvmti.so
BUILD: Doing 'make -j4' parallel build
...
CC jvmti/libjvmti.o
CC jvmti/jvmti_agent.o
LD jvmti/jvmti-in.o
LINK libperf-jvmti.so
$ make DESTDIR=/tmp/krava/ install-bin
...
$ find /tmp/krava/ | grep libperf
/tmp/krava/lib64/libperf-jvmti.so
/tmp/krava/lib64/libperf-gtk.so

Tested the patch on x86_64. With and without NO_JVMTI.
Tried the libperf-jvmti.so on existing test case, got correct results.
I believe you can now remove the jvmti/Makefile, it is not needed
anymore. We must always (and only) build the .so as this library
is meant to be used as a Java agent.
