(In reply to Eugene Grosbein from comment #8)
Hm as a crutch we could add something to llvm.build.mk to lower the
optimization level when TOOLS_PREFIX is unset (e.g. when the cross-tools stage
is run). @emaste what's your opinion on this?

E.g. adding something like:

.if !defined(TOOLS_PREFIX)
# Lower optimization level to increase probability of successful bootstrap
CFLAGS+= -O1
.endif

That is rather ugly though. I'd rather have people with low-spec systems use
CFLAGS=-O1 in their /etc/make.conf or /etc/src.conf, or simply use external
toolchains.
