gdb: Make GMP a required dependency for building GDB
This commit modifies gdb's configure script to trigger an error
if we cannot find a usable libgmp.
For the record, making this a requirement was discussed in March 2018:
https://sourceware.org/pipermail/gdb-patches/2018-March/147373.html
gdb/ChangeLog:
* configure.ac: Generate an error if a usable GMP library
could not be found.
* configure: Regenerate.
