[PATCH] XCore target: add support to build MultiSource/Benchmarks/SciMark2-C

[robert lytton]

robertlytton added you to the CC list for the revision "XCore target: add support to build MultiSource/Benchmarks/SciMark2-C".

The xcore target is ending up with -ve zero instead of +ve zero.
Is this an important difference?
If not, is it reasonable to use abs()?
