Are you sure you're using the correct assembler?

Try tweaking your PATH so that symlinked names for the ARM toolchain are
all on your PATH before your host toolchain.

If that's not the issue then its presumably an issue with Pg's configure
script/Makefiles invoking the wrong tool in a cross-compile situation,
because AFAIK there's no ARM asm code or ARM gcc intrinsics hidden away
in Pg, and that'd be the only other way to get those kinds of errors.
