No dice.  Even a clean build of tools, etc. won't work around this.  As
suggested, I added 2GB more swap via a swap file (for 2GB RAM+4GB swap)
and it still failed with:

[...]

I've been trying to figure out where I can override the optimization
flag for just this one source file, for only the architectures I've
observed failing, but I haven't had any success.

The seemingly obvious file is "src/external/mit/xorg/lib/libmesa.mk",
followed, perhaps by "src/external/mit/xorg/lib/gallium/Makefile", but
CFLAGS alteration in these would be applied to all files, not just
"format_utils.c".

There seemed to be a "CFLAGS.<sourcefile>" construct to permit per-source
setting of CFLAGS contents, but it had no effect when I tried it.  Perhaps
I put it in the wrong place?

Hints?
