libgcc: aarch64: Do not use .previous after build attributes

.aeabi_subsection selects the current AArch64 build-attribute
subsection, not the current ELF section.  The following .previous
therefore does not return from the build-attribute subsection.  In
aarch64-asm.h it instead switches back to .note.GNU-stack, which was the
previous ELF section after emitting the non-executable stack note.

Remove the .previous from the build-attribute marking path.  Keep it in
the GNU_PROPERTY path, where it matches the explicit switch to
.note.gnu.property.

libgcc/ChangeLog:

	* config/aarch64/aarch64-asm.h (FEATURE_1_AND_MARK): Do not emit
	.previous after AArch64 build attributes.
