Also recognized are aarch64-*-gnu tagrets, e.g. aarch64-pc-gnu or aarch64-unknown-gnu. The ld/emulparams/aarch64gnu.sh file is (for now) identical to aarch64fbsd.sh, or to aarch64linux.sh with Linux-specific logic removed; and mainly different from the generic aarch64elf.sh in that it does not set EMBEDDED=yes. Coupled with a corresponding GCC patch, this produces a toolchain that can sucessfully build working binaries targeting aarch64-gnu. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com>
