Currently the presence of a feature is checked with a combination of
perf version --build-options and greps, such as:
perf version --build-options | grep " on .* HAVE_FEATURE"
Instead of this, introduce a subcommand "perf check feature", with which
scripts can test for presence of a feature, such as:
perf check feature HAVE_FEATURE
'perf check feature' command is expected to have exit status of 0 if
feature is built-in, and 1 if it's not built-in or if feature is not known.
Multiple features can also be passed as a comma-separated list, in which
case the exit status will be 1 only if all of the passed features are
built-in. For example, with below command, it will have exit status of 0
only if both libtraceevent and bpf are enabled, else 1 in all other cases
perf check feature libtraceevent,bpf
The arguments are case-insensitive.
An array 'supported_features' has also been introduced that can be used by
other commands like 'perf version --build-options', so that new features
can be added in one place, with the array
Committer testing:
$ perf check feature libtraceevent,bpf
libtraceevent: [ on ] # HAVE_LIBTRACEEVENT
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
$ perf check feature libtraceevent
libtraceevent: [ on ] # HAVE_LIBTRACEEVENT
$ perf check feature bpf
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
$ perf check -q feature bpf && echo "BPF support is present"
BPF support is present
$ perf check -q feature Bogus && echo "Bogus support is present"
