This reverts commit49db4a3a15,9f1f0104f1,4f95c14adf,c34dc64028,570fdcd251,4bff0298c5and6939aee0c0. When relying on Clang config files, two issues appeared: - Running the compiler-rt tests fails, because the compiler-rt tests disable any default config files, breaking the compiler in this case: https://github.com/llvm/llvm-project/blob/llvmorg-19.1.1/compiler-rt/test/lit.common.cfg.py#L983 - Wine fails to build using llvm-mingw as cross compiler, because Wine adds the --no-default-config flag to Clang while compiling, if supported: https://gitlab.winehq.org/wine/wine/-/blob/wine-9.19/configure.ac?ref_type=tags#L866-868 This causes llvm-mingw to omit the -rtlib=compiler-rt option (specified in a config file), making the compiler look for libgcc instead. Doing a check to see that linking succeeds doesn't necessarily help here - such a check already exists, but it tests linking with -nostdlib -nodefaultlibs: https://gitlab.winehq.org/wine/wine/-/blob/wine-9.19/aclocal.m4?ref_type=tags#L193-L206
