make -j doesn't have any effect with toybox, it detects its own SMP
level (set CPUS=1 to override that).

So that worked?

Ah, back in November I fixed it for scripts/make.sh and
scripts/install.sh but missed the HOSTCC?=cc in the makefile. Which is
being used to build a generated/instlist that scripts/install.sh doesn't
use (it builds its own), so...

Try now?

Which was suggested at the time, and broke stuff because CFLAGS is
target options (ala "select big endian"), not host options. It's
host/target confusion, the basic problem with cross compiling.

I just pushed a commit that should fix it, I think? (I still don't have
this build environment...)
