gem5/ext/softfloat/SConscript
Gabe Black 64d1297d86 scons: Move the build of ext/ into the variant dirs. 
These are no longer split out and shared in the root build/ directory.
This does result in a small amount of overhead from building redundant
copies of these files, although the overhead is not significant. When
building 7 different variants of gem5, all the ISAs and NULL, the
difference on my machine was:

Before:
real    41m25.372s
user    914m22.266s
sys     41m51.816s

After:
real    42m38.074s
user    921m36.852s
sys     43m2.949s

This is about a 2-3% difference, which is a worse than typical case,
since the overhead scales with the number of variants being built.

The benefit of pulling ext/ into the variant directory is that there can
now be a single config which applies to all files used to build gem5,
and that config is represented by the variant of gem5 being built.
