libgcobol: Heed --enable-libgcobol
If some target isn't listed as supported in configure.tgt,
--enable-libgcobol cannot override that. However, that's what should
happen just like an explicit --enable-languages=cobol forces the
frontend to be built.
This patch, shamelessly adapted from libphobos, does just that.
Tested on amd64-pc-solaris2.11, sparcv9-sun-solaris2.11, and
x86_64-pc-linux-gnu.

libgcobol:
* configure.ac: Handle --enable-libgcobol.
Let it override LIBGCOBOL_SUPPORTED.
* configure: Regenerate.
