Well, my point was to not break anything :)

On my way through the possible architecture names
(binutils-gdb/gdb/features/*.xml), I wasn't able to come up with the right name
for arm 32 bit (arm-core.xml) - they don't specify any. This patch therefore
adapts to the xml files from gdb.

The architecture should be known at the same point when specifying the xml file.
So if anyone can come up with the proper arm name in the future (or even some
kind of detection algorithm), it can simply be set in target-arm/cpu.c (after
"arm-core.xml").
