I think we've reached the point where the following target
configurations should be End-of-Life'd. As such, I'd like to mark them
as deprecated in gcc-4.7, prior to removal after the branch.
I'd also like to remove at that time support for some now obsolete
co-processor units, namely the FPA and Maverick.
For the time being I've kept the ecos-elf and the legacy RTEMS targets,
but I'm hereby putting them on notice as candidates for deprecation in
the next cycle. RTEMS how has an EABI conformant port, and ecos-elf
really should be moved in that direction too, if it is not to end up
dead very quickly.
* config.gcc (arm*-*-elf, arm*-*-linux-gnu): Deprecate.
(--with-fpu={fpa,fpe*,maverick}): Likewise.
