When building with LLVM_IAS=1, there is no point to specifying '--prefix=' because that flag is only used to find the cross assembler, which is clang itself when building with LLVM_IAS=1. All of the other tools are invoked directly from PATH or a full path specified via the command line, which does not depend on the value of '--prefix='. Sharing commands to reproduce issues becomes a little bit easier without a '--prefix=' value because that '--prefix=' value is specific to a user's machine due to it being an absolute path.

Reviewed-by: Fangrui Song <maskray@xxxxxxxxxx> clang can spawn GNU as (if -f?no-integrated-as is specified) and GNU objcopy (-f?no-integrated-as and -gsplit-dwarf and -g[123]). With LLVM_IAS=1, these cases are ruled out.
