I'm trying out the new build process, and am seeing an error in 
building libgcc2. I'm thinking its because the build is using 
the native compiler rather than TOOLDIR/bin/i386--netbsdelf-gcc.

I added CFLAGS+=-v into mk.conf and got the following output 
when the build failed. (This is after the tools have been built, 
during the do-gnu-lib stage.)

Stop.

Somebody want a send-pr on this?
