My patch last week to address selection of be8 linking mode broke the
build for vxworks. It turns out that this port is one of the few
remaining that is still not based on the EABI/AAPCS.
This patch fixes the build, but I've not really tested it beyond
building the core compiler binaries. Building a workable compiler
entails downloading a load of vxworks stuff that I'm not sure where to find.
The port is also *very* out-of-date. Not only does it not use the EABI,
but it hasn't had support for any core added since ARMv5 (and ARMv6 was
announced in 2002)!
I therefore propose that we consider this port for deprecation.
