GCC's AMD GCN (alias Radeon) target (most useful for offloading) uses LLVM's assembler as GNU Binutils does not support GCN (yet?).

Many Linux distributions build GCC with offloading support for nvptx and amd gcn (installable was optional add-on packages).

The issue was found as building GCC was breaking on Debian once LLVM 11.0.0 was imported into Debian unstable. (Happens during the build of newlib's libc for GCN; this uses -ffunction-section). First reported at https://gcc.gnu.org/PR97827
