@Prabhuk I might need some help here. Looking at the output for the `Clang :: Driver/DTLTO/dtlto.c test` on your buildbot LLD is being invoked with the argument `"--thinlto-remote-compiler=/b/s/w/ir/x/w/llvm_build/bin/llvm"`. That is clearly not the location of a Clang compiler! This is produced by calling ToolChain.getDriver().getClangProgramPath() in the Clang driver (see: https://github.com/llvm/llvm-project/commit/5004c59803fdeb3389d30439a6cc8b1ff874df0c#diff-c89ebf1fc950679f63c19739a35aa966a12674f7d61af6fb382ab1fa0ee21dd7R1328). Is there something strange about the buildbot or perhaps the `fuchisa` target that might lead to this?
