Move a copy of amd64's debug code into debug.ldscript. Make all the kernels use this. This has the effect of modernizing the STABS for powerpc as the others were almost already in sync. For the ones that weren't this adds the DWARF 3 debug symbols from i386/amd64. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D44071
