static link + pkg-config assistance

[Ben Magistro]

I completely missed that so thanks for pointing it out.

On the CentOS environment I don't have an easy way to update it right now
so I switched over to another host and am seeing similar behavior.  The
major deltas are listed below.

OS: Ubuntu 21.10
meson: 0.56.2
pkg-config: 0.29.2 (+ 1.7.3 via pkgconf)
gcc: 11.2.0
