Rollup merge of #109156 - taiki-e:linker-detection, r=petrochenkov 
Fix linker detection for clang with prefix

https://github.com/rust-lang/rust/pull/106489 removed check for clang with prefix. It says:

> Also remove the check for -clang, since there are no architecture specific variants of clang (to my knowledge).

However, when doing cross-compilation, a wrapper script for clang with the target name as a prefix is sometimes used.

1716932743/compiler/rustc_target/src/spec/aarch64_pc_windows_gnullvm.rs (L7)

It seems the regression did not occur on the targets mentioned above because the default linker flavor is gcc, but it did occur on targets where the default linker flavor is not gcc (fd352f3ffa).
