Okay---cool.

The libdir & incdir stuff would be for such a case:
To compile against libfoo, you need to include a non-standard path
such as -I/usr/include/libfoo/bar/. Normally pkgconfig just adds this
flag but the path (pre-pkgconfig.bbclass) is gross (<staging
path>/usr/include/libfoo/bar/); the pkgconfig.bbclass strips this down
to a floating 'libfoo/bar' in the flags line when it should be
'-I/usr/include/libfoo/bar'.

I think the patch as I submitted it doesn't fix this properly for all
cases.  Also relies on ${prefix} to be correctly set for
pkgconfig---is this a safe assumption?

Should I split out the -rpath-link and -isystem into a separate patch?

Thanks,
