the makefiles use CPU_TARGET, but this shouldn't be necessary when
you're compiling natively (or inside an emulator, even).

i'd recommend going the cross compile route (since i know that works
with trunk).  just compile binutils (./configure --target arm) and
compile fpc with:

make crossall CPU_TARGET=arm CROSSOPT="-CfSOFT"

you can use other envvars, too, just inspect the makefile if you're
brave, or read the buildfaq for some good info.
