Improve gdb.base/float128.exp failure message
If the "print large128" sub-test fails in a manner that typically
indicates internal overflow due to GDB being built without MPFR
support, explicitly state this in the failure message.
gdb/testsuite/ChangeLog:
2018-06-20 Ulrich Weigand <uweigand@de.ibm.com>
* gdb.base/float128.exp: Add comment and improved fail message
to the failure case of "print large128" test.
