[Bug target/100208] amdgcn fails to build with llvm-mc from llvm12
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100208 --- Comment #1 from Andrew Stubbs --- LLVM changed the default parameters, so we either have to change the expectations in the ".amdgcn_target" string (which is basically an assert), or set the attributes be want explicitly on the assembler command line. (Or port binutils to amdgcn, but there's no plan for that.)
