gcc version 7.3.0 (GCC)
produces the following error when called with --help=target (or other class):
cc1: error: position-independent code requires ‘-mabicalls’
The error is issued in mips_option_override because it is called
earlier than finish_options where the proper default value
global_options.x_flag_pic=0 is set. When mips_option_override is
called, global_options.x_flag_pic==-1.
Probably mips_option_override should check the condition (flag_pic > 0).
