  The GMP variant of Ada.Numerics.Big_Numbers.Big_Integers is currently
not used, but since we keep it, it seems worth to keep it up-to-date
with respect to the corresponding spec.

Part of providing a gdb pretty-printer for Big_Integer objects.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* libgnat/a-nbnbin__gmp.adb (From_String): Fix predicate
	mismatch between subprogram declaration and body.
