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.

$ make VF=1
BUILD: Doing 'make -j4' parallel build

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

SNIP

... 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 ]
