[PATCH][GAS] arm: add armv9-a architecture to -march

[Martin Liška]

Hello.

A question: I'm building cross GCC compiler with the latest binutils master,
as I see:

Error: unknown architecture `armv9-a'

Where I configure binutils with --enable-targets=...,armv9l-suse-linux.
What am I doing wrong?

Can you please add a GAS test-case that 'armv9-a' is accepted for .arch directive?

Thanks,
Martin
