GDB can call function i386_target_description to get the right target
description rather than tdesc_i386.
gdb:
2017-08-18 Yao Qi <yao.qi@linaro.org>
* amd64-fbsd-nat.c (amd64fbsd_read_description): Call
i386_target_description.
* i386-fbsd-nat.c (i386fbsd_read_description): Call
i386_target_description.
* i386-tdep.c (i386_gdbarch_init): Likewise.
