system/gcc: Make ARMv7 unwind macros functions
This workaround is already needed upstream for FreeBSD. Let's go ahead and use the same workaround for musl. We also ensure they are not declared `inline` so that they are available as library functions. We also have a hack in place for the stage1 Ada driver due to their own hack pulling in the Arm unwind functions directly without linking. Fixes: #866 (and probably more as we continue building packages)
