This was a known issue in GDB 13.1, It has been fixed/changed on the
trunk and will be included with GDB 14. For pre-GDB 14, the option you
want to use for configure is --with-libgmp-prefix= . libmpfr is
similar you need to use --with-libmpfr-prefix .
These options are documented in the installation documentation for GDB
13 but they were not part of the toplevel configure which is why they
were not mentioned there. The options --with-gmp= and --with--mpfr=
were only originally used for building GCC (GCC, GDB, binutils [and
newlib] all share the same toplevel configure/make file system) and
this was why folks got confused and even more I made the fix for this
to use these options also for GDB.

This issue was recorded as
https://sourceware.org/bugzilla/show_bug.cgi?id=28500 .
