aarch64: fix asm visibility for extern symbols

Commit r271869 broke visibility declarations in asm for extern symbols, because
the new ASM_OUTPUT_EXTERNAL hook failed to call the default hook for elf.

gcc/ChangeLog:

	* config/aarch64/aarch64-protos.h (aarch64_asm_output_external): Remove
	const.
	* config/aarch64/aarch64.c (aarch64_asm_output_external): Call
	default_elf_asm_output_external.

From-SVN: r271913
