assembly support broken

[git-bruh]

The assembly support added in #2545 seems to be broken, when executing distributed compilation, the -x argument generated for the compiler is invalid (file contents irrelevant):

$ sccache cc -c test.S
sccache: Job failed on server 192.168.1.3:10600:
cc: error: language assembler-with-cpp-cpp-output not recognized
cc: error: language assembler-with-cpp-cpp-output not recognized
sccache: Compiler killed by signal 1

Seems to be due to this condition:

sccache/src/compiler/gcc.rs

Line 915 in d9d2eb6

_ => language.as_mut()?.push_str("-cpp-output"),

TIA for looking into this!

Hi @git-bruh ,

Thanks for the bug finding.

Please, check the #2557 for the possible fix. Is it works for you?

Seems to work, thanks!
