Apply e2ffa15b9baa and fde0ab43b9a3 to 6.12

Hi Greg and Sasha,

Please apply

e2ffa15b9baa ("kbuild: Disable CC_HAS_ASM_GOTO_OUTPUT on clang < 17")

and its follow up fix

fde0ab43b9a3 ("Fix CC_HAS_ASM_GOTO_OUTPUT on non-x86 architectures")

to 6.12, as it helps avoid bogus errors around cleanup variables.

If there are any issues, please let me know.

Cheers,
Nathan
