arm-rtems vs. arm-elf

[Joel Sherrill <joel dot sherrill at OARcorp dot com>]

Hi,

arm-elf seems to build fine but arm-rtems fails on a thumb variant 
on libgcc2.c.  arm-rtems is a simple wrapper for arm-elf and I 
can't see enough differences in the binutils or gcc configurations
to justify this failure.  Any thoughts?
