No, pkgconfig should support files in /usr/share/pkgconfig/ and so
should dpkg-cross.

The issue is that the pkgconfig files in /usr/share/ never seem to
contain any useful data, yet packages still look for just the file.
None of the pkgconfig files in my /usr/share/pkgconfig/ contain any
data for --cflags or --libs

neil@dwarf:~$ pkg-config --cflags pthread-stubs
neil@dwarf:~$ pkg-config --libs pthread-stubs
I'm not sure why pthread-stubs-dev contains a pkgconfig file that
provides no pkgconfig data but that is common to all the pkgconfig
files in /usr/share/pkgconfig/ so it's reasonable for dpkg-cross to
handle them (to prevent build errors against the -dev package
using /usr/share/pkgconfig/), even if nothing useful is actually inside
the files.

That change will be in dpkg-cross 2.3.4:
