--- Display state of the rest of the features (FEATURE_TESTS_EXTRA) for 'make VF=1' build. These features are detected manually by perf's Makefile.config so they can't be displayed with the main list, but only after we're done in Makefile.config.

Auto-detecting system features: ... dwarf: [ on ] ... dwarf_getlocations: [ on ] ... glibc: [ on ] ... gtk2: [ on ]

... timerfd: [ on ] ... sched_getcpu: [ on ] ... sdt: [ on ] ... setns: [ on ]
extra features: ... bionic: [ OFF ] ... compile-32: [ on ] ... compile-x32: [ OFF ] ... cplus-demangle: [ on ] ... hello: [ OFF ] ... libbabeltrace: [ on ] ... liberty: [ on ] ... liberty-z: [ on ] ... libunwind-debug-frame: [ OFF ] ... libunwind-debug-frame-arm: [ OFF ] ... libunwind-debug-frame-aarch64: [ OFF ]
