[PATCH] Regenerate gas/config.in and ld/configure

[PATCH] Regenerate gas/config.in and ld/configure

[Mark Wielaard]

commit d173146d9 "MIPS: Change all E_MIPS_* to EF_MIPS_*"
changed gas/config.in to rename USE_E_MIPS_ABI_O32 to USE_EF_MIPS_ABI_O32
this new name sorts differently when regenerating gas/config.in

commit e922d1eaa "Add ability to change linker warning messages into
errors when reporting executable stacks and/or executable segments."
Introduced two new help strings for --enable-error-execstack and
--enable-error-rwx-segments in configure.ac which weren't included
in ld/configure when regenerated.

	* gas/config.in: Regenerate.
	* ld/configure: Likewise.
---

Martin Jambor has a script from Martin Liska which can regenerate
and check auto* files are properly created with the intended autoconf
and automake version for gcc. We adapted it to binutils and added
a buildbot to use the script to check the binutils-gdb git repo.
It found these two small discrepancies. OK to push?

Apologies, the below should of course have gone to binutils not
gdb-patches. The script runs for the whole binutils-gdb git repo
though.
