Try this patch, which provides an alternative implementation of the 64-bit integer negation operation MAD_F_MLN which works around the lack of the RSC instruction in Thumb-2.

A missing earlyclobber constraing flag in the existing implementation is also fixed by the patch.

This fixes the build failure and I believe the code works... can anyone suggest how best to test it? (There seems to be no make check or make test).
