This patch makes x86-64.h pass "--64" to the assembler when compiling
in 64-bit mode.
There are several advantages:
1. For a bi-arch compiler for which 32-bit code is the default, we no
longer need to override ASM_SPEC.
2. We get earlier failure and better error messages from the assembler
if the user tries to use a 64-bit compiler with a 32-bit assembler.
OK?
