[PATCH 04/15] tools build: Add jvmti feature detection support

Show all headers | View raw

From: Jiri Olsa <jolsa@kernel.org>

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.
