debug/gdb: add option to use GMP and MPFR

GMP and MPFR are optional for gdb, so offer a config option.
     1 # Build script for the gdb debug facility
     2 
     3 # The version of ncurses to use. Yes, it's hard-coded.
     4 # It's used only internally by crosstool-NG, and is
     5 # not exposed outside, so we don't care about providing
     6 # config options for this.
