Use BOOT_CFLAGS. Those flags will be used by the stage2/stage3 builds.
Note that on a sparc, -O2 implies -fomit-frame-pointer and
-fexpensive-optimizations. Also nte that -ffunction-sections isn't going
to improve runtime performance without using linker scripts to drive
placement of functions.

You need a recent dejagnu snapshot. They can be found on the egcs
ftp server in the "infrastructure" directory.

loop-2f is known to fail on sparcs.

I would suspect you've got an out of date dejagnu.
