Ok. It's true that having an already existing cross-compiler and
Buildroot installation in the PATH can possibly cause some issues,
though I'd like this to work properly.

Can you give us the contents of host/usr/bin/pkg-config ? It is a
wrapper shell script that sets a bunch of variables and calls pkgconf.
I would nonetheless like to have your full "foo.log", to see more
precisely what's going on with pkg-config.

It is possible, just don't have one in the PATH in a permanent way. The
way I typically do things is by adjusting the PATH only in the
shell/terminal I'm going to use the toolchain, or even use the full
Again, I believe we should continue to investigate this some more, I'd
like to understand the root of the problem and see if there's a
reasonable fix for it (even though I believe there might be several
other issues in trying to do a Buildroot build with an existing
Buildroot build in the PATH).
