config.gcc: Add new case statement to set default_gnu_indirect_function.

2017-09-22  Steve Ellcey  <sellcey@cavium.com>

	* config.gcc: Add new case statement to set
	default_gnu_indirect_function.  Remove it from x86_64-*-linux*,
	i[34567]86-*, powerpc*-*-linux*spe*, powerpc*-*-linux*, s390-*-linux*,
	s390x-*-linux* case statements.   Added aarch64 to the list of
	supported architectures.
