GCC support for i386

[Joel Sherrill]

I couldn't find any pure i386 applications when I asked last time. That was for dropping soft float support. My concern was use of space hardened i386 and non-Intel cpus like the Geode which might effectively be i386.

I understand on x86 but don't want this to turn into a general minimum requirement to have atomics.

The i386 is a bit special since x86 is the GCC main stream architecture.  I
asked this out of curiosity.  Is there really some working i386 hardware around
with RTEMS on it?
