When building with clang and RV32F enabled, linking fails with undefined references to SoftFloat functions. For example:

$ make CC=clang-18

/usr/bin/ld: /tmp/lto-llvm-28abb9.o: in function do_fmadds': emulate.c:(.text.do_fmadds+0x3c): undefined reference to f32_mulAdd'
/usr/bin/ld: /tmp/lto-llvm-28abb9.o: in function do_fadds': emulate.c:(.text.do_fadds+0x31): undefined reference to f32_add'

This happens because GNU ar cannot correctly archive objects compiled with clang. Switch to llvm-ar when CC is clang, ensuring the SoftFloat library is archived correctly and the build succeeds.

CI: Add llvm-18 bin directory to GITHUB_PATH
ced9e41 
Ensure that llvm-ar and other LLVM tools from version 18 are available
in the PATH during CI builds. Without this, only the versioned binaries
(e.g. llvm-ar-18) are found, which can cause build failures when
unversioned tool names are expected.

When building with clang and RV32F enabled, linking fails with
undefined references to SoftFloat functions. For example:

I ran make CC=clang-18 on my machine with RV32F enabled, and the build completed without errors. Could you provide more details on how to reproduce the issue on your side?

I only ran make CC=clang-18 and hit the build error.
