Looks good.  I'll try it, thanks.

Yes.  I haven't gotten around to that.

A simpler way to go for the moment is to simply add -fno-unit-at-a-time
to CFLAGS when building glibc-2.2.5 with gcc-3.4.x.
That's a bit awkward to add to my demo scripts at the moment.
Maybe I should add an EXTRA_TARGET_CFLAGS variable to crosstool.sh,
and set it only from toolcombo .dat files.  Then
gcc-3.4.2-glibc-2.2.5.dat could set 
EXTRA_TARGET_CFLAGS="-fno-unit-at-a-time"
