perf tools: Add file-handle feature test
The file handle (FHANDLE) support is configurable so some systems might not
have it. So add a config feature item to check it on build time so that we
don't add the cgroup tracking feature based on that.
Committer notes:
Had to make the test use the same construct as its later use in
synthetic-events.c, in the next patch in this series. i.e. make it be:
struct {
struct file_handle fh;
uint64_t cgroup_id;
} handle;
To cope with:
CC /tmp/build/perf/util/cloexec.o
util/synthetic-events.c:428:22: error: field 'fh' with CC /tmp/build/perf/util/call-path.o
variable sized type 'struct file_handle' not at the end of a struct or class is a GNU
extension [-Werror,-Wgnu-variable-sized-type-not-at-end]
struct file_handle fh;
^
1 error generated.
Deal with this at some point, i.e. investigate if the right thing is to
remove that -Wgnu-variable-sized-type-not-at-end from our CFLAGS, for
now do the test the same way as it is used looks more sensible.
