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.
* testsuite/ld-aarch64/aarch64-elf.exp: Run the new test.
