perf build: Add feature-dump target
To provide FEATURE-DUMP into $(FEATURE_DUMP_COPY) if defined, with no further action.
Get feature dump of the current build: $ make feature-dump BUILD: Doing 'make -j4' parallel build
Auto-detecting system features: ... dwarf: [ on ]
FEATURE-DUMP file available in FEATURE-DUMP
Get feature dump static build into /tmp/fd file:
$ make feature-dump FEATURE_DUMP_COPY=/tmp/fd LDFLAGS=-static BUILD: Doing 'make -j4' parallel build
Auto-detecting system features: ... dwarf: [ OFF ]
SNIP
FEATURE-DUMP file copied into /tmp/fd
