- Remove HAVE_GNU_AS: Adjust for GCN assembler ('llvm-mc')
- tldr
- GCC's GCN target now correctly uses 'llvm-mc' as its assembler, resolving issues with the '-v' driver option.

This commit adjusts GCC’s configuration to properly handle the GCN target, which uses LLVM’s ‘llvm-mc’ as its assembler instead of GNU’s as. A previous commit removed the HAVE_GNU_AS check without accounting for this GCN-specific assembler setup. Consequently, GCC incorrectly passed the ‘-v’ driver option to ‘llvm-mc’, causing assembly failures and test regressions. The fix defines ASM_V_SPEC for the GCN target to prevent this incorrect option forwarding.
