Possibly, yes. Maybe we can clarify the gas/gas_flag/with_gnu_as mess
at some later point.
Alternatively, we could do something similar to what we had before:
* Use --32 on i?86-*-linux*:*
--x32 on x86_64-*-linux-gnux32:*
--64 on x86_64-linux*:*
* Use --32 on i?86-*-solaris2*:yes
--64 on x86_64-*-solaris2*:yes
either in separate cases or merged into the Linux/x86 ones, whatever
is clearer.
* Use -arch i386 on i?86-*-darwin*:no
-arch x86_64 on x86_64-*-darwin*:no
* Leave it empty/unset otherwise, just like before.
That's probably the safest for now.
