This shouldn't be an issue.  When building for a different target
system, the packager should be using a host-prefixed pkg-config that
reads .pc files configured for the target.

The issue is that the prefix passed to configure is written to the
prefix variable for Hurd's Makefiles, and packagers are overriding
that variable in "make install" to work around the lack of a DESTDIR
variable.

In my opinion, the current behavior for getting XKB_BASE is correct
(reading xkeyboard-config.pc for the actual target systems' path with
"$datadir/X11/xkb" as a good fallback).  The real fix here is to
support a staging installation directory for packagers by implementing
DESTDIR.

Thanks.
