gdb-4.16.85 --with-mmalloc broken under SunOs 4.1.x

When GDB is configured --with-mmalloc under SunOs 4.1.x sparc/m68k, the
resulting GDB issues the following warning upon startup:

warning: failed to install memory consistency checks; 
configuration should define NO_MMCHECK or MMCHECK_FORCE

This is caused by inconsistent naming of definitions:
gdb/utils.c uses MMCHECK_FORCE, while gdb/configure.in and gdb/acconfig.h
use FORCE_MMCHECK.

Here is a patch:
