[Bug ada/42518] Alignment issue prevents building 64 bit RTS on Snow Leopard

Sorry if I've caused confusion by misunderstanding the reporting system.

I can build GCC4.4.2[i386-apple-darwin10.2.0] using
GNAT-GPL-2009[i386-apple-darwin10.2.0].

I then try to build GCC4.4.2[x86_64-apple-darwin10.2.0] using
GCC4.4.2[i386-apple-darwin10.2.0], with the reported results.

So the problem arises in the middle of the compiler build process; the original
host compiler was i386-apple-darwin10.2.0 but by the time the error occurs
we're using the stage3 x86_64-apple-darwin10.2.0 compiler (of course it can
never be installed because it can't build its RTS).

I've been using --build=x86_64-apple-darwin10.2.0 to indicate that I want to
build a 64-bit compiler, is that not the right method? (I picked this up from
AdaCore's GNAT-GPL-2009, which is x86_64 built on Leopard; it's not a technique
mentioned in documentation at gcc.gnu.org).
