Update Erlang/OTP to R13B04

Update Erlang/OTP to R13B04 release and in the process drop amd64
and HiPE patches. Geoff Cant provided patches inspired by the
macports diffs and these are now included upstream.

I've also dropped the wxMac patches as (1) wx is not built but
SKIPped and (2) the last time I tried on 10.6 it worked without any
patches. That was of course in 32-bit mode only as the wxMac bundled
with 10.6 is exclusively 32-bit. The not-yet-stable wxMac 2.9 branch
has 64-bit support but it's not tested with wxErlang, yet.
