[PATCH] Support cross compilation

[PATCH] Support cross compilation

[Christopher Baines]

With these changes, I was able to cross-compile guile-lib to the GNU
Hurd, and use part of the library at least.

* configure.ac: Set GUILE_TARGET when cross compiling.
* am/guile.mk: Pass GUILE_TARGET to guild compile.

Hi :)

Which library is this for?  It doesn't appear to be guile itself.
