gmp: configure and acinclude.m4: fix -std=c23 build failure

Browse Source 
Add prototype to configure test function as c23 removes unprototyped
functions.

gcc-15 switched to -std=c23 by default:

    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=55e3bd376b2214e200fa76d12b67ff259b06c212

As a result `configure` fails with:
    conftest.c: In function 'f':
    conftest.c:12:48: error: too many arguments to function 'g'; expected 0, have 6
