Technically, I think we should not have a copy of GMP in our sources.
The libltdl thing is already somewhat confusing: when you first
configure Guile without a libltdl in your system, it will install it.
When you configure a new version of Guile, it will find the old
libltdl and will use it, while it should probably replace it with the
new version from Guile.

I'd say the user should explicitely state that he/she doesn't want to
use GMP.  When --without-gmp is not given, configure should abort when
GMP is not found.  Otherwise people might be tricked into building a
Guile with inferior number support without noticing it.
