This has been a problem for Gentoo as well, so we are simply overriding
it using 1-liner sed:

sed -i -e 's:@toolexeclibdir@:$(libdir):g' Makefile.in

(And making sure the generated libffi.pc after install is still is OK as
a precaution)

I'm just saying as a hint, for any other packagers who don't want the
overly smart logic from
configure to be used.
