Comment(by erikd):

 Ok, with that bad patch chunk removed, it compiles, with these warnings:

 {{{
 rts/Linker.c:1891:16:
      error: 'misalignment' may be used uninitialized in this function
 rts/Linker.c: In function 'loadObj':

 rts/Linker.c:2066:7:
      error: 'misalignment' may be used uninitialized in this function
 }}}

 The stage one compile completes, but it errors out in stage 2 when
 compling the vector library.

 Looking at the code in rts/Linker.c, misalignment is caclucaled by a
 function machoGetMisalignment() which seems to be darwin_HOST_OS specific.
 We need the powerpc-linux version of that function.
