FYI,
It looks like libcap silently fails a gperf check due to which
missing.
If which is installed then libcap build fails with the following:

Probably related to this:
https://bugs.gentoo.org/604802
The question is, how important is libcap being built with gperf.
Regards,
Wayne.
It's not important at all, as the tarball already distributes pre-
generated file (with an older gperf, I guess). Fix the issue with
make BUILD_GPERF=no
We have gperf after libcap, so it is really a non-issue for LFS.
