ld: Add -no-pie
gold has had this option for many years. Not having this option caused some confusion to users. The help message clarifies the default state. ld/ * ldlex.h (enum option_values): Add OPTION_NO_PIE. * lexsup.c (struct ld_options): Add -no-pie. (parse_args): Handle -no-pie. * ld.texi: Document -no-pie.
