Yes, I know.

It should be possible. However, I'm not sure what the best solution
3) Bruno's lib-link.m4 macros.
There are advantages and disadvantages with all.
Bruno's macro is what I prefer, but the disadvantage there is that the
macro requires the 'config.rpath' script. Not all applications have
that script, and copying both a libgnutls.m4 and a config.rpath may be
a bit complicated. Maybe this is a small price to pay?
Pkg-config has the problem that it adds another dependency, and it
seems unclear (to me, not being a pkg-config expert) whether
pkg-config does the right thing for libtool, cross-compilation, and
various platform behaviours (-rpath, -Wl,-rpath, -R, etc). At the
least, it seems that a new libgnutls.m4 could use pkg-config, but
additionally try to link with the library, to check that it works,
before using it. This will help when cross-compiling; e.g., it won't
automatically try to use a i386-linux library when you build for
libgnutls-config is a maintenance problem, but not really a huge
problem, the scripts have only been touched a few times in several
years. The current design seems to have the same problems as
I think we should try to solve this in 1.5.x, before 1.6.
