[PATCH] [x86] Convert little endian Addend to native endian when reading MachO section data.

[Daniel Sanders]

Thanks, r219543 fixes the test. The remaining two failures (MachO_ARM_PIC_relocations.s and MachO_i386_eh_frame.s) are looking like the same kind of thing but I haven't located the origin of the endian-reversed value yet.
