#4828: ghci fails to load fat binary archives on OS X

Architecture: Unknown/Multiple | Failure: GHCi crash
---------------------------------+------------------------------------------
ghci crashes when loading fat binary archives (i.e., multi-architecture
`.a` files) on OS X. From looking at `rts/Linker.c`, the fat header isn't
parsed at all.
This isn't hard to fix, it's just a matter of examining the fat header
structure, computing the offset to the host architecture in the archive,
and continuing with the processing in `loadArchive`.
This bug affect people who build universal architecture libraries on OS X.
The only workaround now is to rebuild the library for a single
architecture.
It would be good to get this fixed for 7.0.2; I'll try to produce a patch
within a week.
