gdb: fix build with x32

When compiling gdb for x32, it fails with errors:

Subject: [PATCH] Unbreak GDBserver build for x32
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When I verify my target description changes, I build GDB and GDBserver for
x32, but it failed.

ipa_x32_linux_regobj use to be there, but removed by

gdb/gdbserver:
2017-08-04 Yao Qi <yao.qi@linaro.org>
* configure.srv (ipa_x32_linux_regobj): New.
* linux-amd64-ipa.c (get_ipa_tdesc): Use X86_TDESC_AVX_AVX512
instead of X86_TDESC_AVX512.
(initialize_low_tracepoint): Call
init_registers_x32_avx_avx512_linux.
