    scripts/Makefile.clang: default to LLVM_IAS=1 · f12b034a
    Nick Desaulniers authored
    LLVM_IAS=1 controls enabling clang's integrated assembler via
    -integrated-as. This was an explicit opt in until we could enable
    assembler support in Clang for more architecures. Now we have support
    and CI coverage of LLVM_IAS=1 for all architecures except a few more
    bugs affecting s390 and powerpc.
    
    This commit flips the default from opt in via LLVM_IAS=1 to opt out via
    LLVM_IAS=0.  CI systems or developers that were previously doing builds
    with CC=clang or LLVM=1 without explicitly setting LLVM_IAS must now
    explicitly opt out via LLVM_IAS=0, otherwise they will be implicitly
    opted-in.
    
    This finally shortens the command line invocation when cross compiling
    with LLVM to simply:
    
    $ make ARCH=arm64 LLVM=1
