Tidy warn-execstack handling
Make ld and bfd values consistent by swapping values 0 and 2 in
link_info.warn_execstack. This has the benefit of making the value an
"extended" boolean, with 0 meaning no warning, 1 meaning warn, other
values a conditional warning.
Yes, this patch introduces fails on arm/aarch64. Not a problem with
this patch but an arm/aarch64 before_parse problem.
bfd/
* elflink.c (bfd_elf_size_dynamic_sections): Adjust
warn_execstack test.
include/
* bfdlink.h (warn_execstack): Swap 0 and 2 meaning.
ld/
* configure.ac (DEFAULT_LD_WARN_EXECSTACK): Use values of 0,
1, 2 consistent with link_info.warn_execstack.
* ld.texi: Typo fixes.
* lexsup.c (parse_args): Adjust setting of link_info.warn_execstack.
(elf_static_list_options): Adjust help message conditions.
* configure: Regenerate.
