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.
