[PATCH][ARM] Fix RVCT interoperation issue

[Andrew Stubbs]

The attached patch, submitted on behalf of Dan Jacobowitz, fixes an 
unwind bug when using RealView and libgcc.

It's an old patch that has been in CodeSourcery and Linaro toolchains 
for sometime, but somehow escaped being posted here.

OK? (For stage 1?)
