Browse Source 
GDB can call function i386_target_description to get the right target
description rather than tdesc_i386

2017-09-04  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.
