Subject: Fix accesses to the GOT for AARCH64 operating in 32-bit mode.

	PR ld/20868
bfd	* elfnn-aarch64.c (elfNN_aarch64_tls_relax): Use 32-bit accesses
	to the GOT when operating in 32-bit mode.

ld	* testsuite/ld-aarch64/tls-relax-gd-ie-ilp32.d: New test.
	* testsuite/ld-aarch64/relocs-ilp32.ld: Linker script for the new
	test.
