Comment (by bgK):

 Yes, it's related to this PR. We now define PKG_CONFIG_LIBDIR when
 automatically running configure, so that its value is saved between runs
 (useful for the cross-compilation case). There are two main
 implementations of pkg-config. The one from freedesktop.org and the one
 from github.com/pkgconf/. The one from github ignores PKG_CONFIG_LIBDIR
 when it is empty and uses the system .pc lookup directories. The one from
 fd.o does not and uses an empty search path...
 We probably need not to set PKG_CONFIG_LIBDIR when the saved value is
 empty, or something like that.
