[PATCH 0/5] perf build: nondistro build tidyups

[James Clark]

nondistro builds now require a specific version of libbfd, so this adds
an error when doing an explicit BUILD_NONDISTRO build and some other
related tidyups.

I'm not sure if the intention is to skip build-tests if something is
missing, but I see it was done for libbpf versions, so I added the same
for libbfd. This is the main thing that I hit, that build-test all of a
sudden stopped working for me.

The first commit is also a cherry pick of an old commit that seemed to
have been accidentally reverted in the unrelated change linked in the
trailers.
