[Boost-build] Patch: use correct linker options on AIX gcc builds

Hi,

When building gcc on AIX, it is apparently usual to use the system 
linker and not the ld from GNU binutils. See for example 
http://gcc.gnu.org/ml/gcc-bugs/2005-12/msg01523.html (gcc doesn't even 
compile on AIX 5.3.0.0 using ld from GNU binutils, in fact).

The below patch sets the correct options for building with gcc, using 
the native linker, on AIX.

Patch is released under the Boost Software License version 1.

Best wishes,
Andrew
