Thanks for the tip!  For this situation, my change looks like:

The end result is the compiler command line has "-O2" early on but has
"-O1" later, overriding the previous optimisation flag.  With this change,
"format_utils.c" compiles and my build of macppc w/gcc48 is proceeding.
I will back up to sparc and evbmips-mips64el to confirm once it finishes.
