Committed, sim/cris: a few updates to the AUX vector passing

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

Mostly simplifications: there's no use having TARGET_* macros
that are standard ELF definitions, duhm and I never used the
value-parameter to AUX_ENTF.  Also, I'd better pass AUX_SECURE
for new kernels, says the glibc source.  Unfortunately I don't
know a simple enough way to add a test-case for this...

Committed.  That's the last for now!

sim:
	* cris/sim-if.c (TARGET_AT_NULL, TARGET_AT_PHDR, TARGET_AT_PHENT)
	(TARGET_AT_PHNUM, TARGET_AT_PAGESZ, TARGET_AT_BASE)
	(TARGET_AT_FLAGS, TARGET_AT_ENTRY, TARGET_AT_UID, TARGET_AT_EUID)
	(TARGET_AT_GID, TARGET_AT_EGID, TARGET_AT_HWCAP)
	(TARGET_AT_CLKTCK): Remove redundant macros.
	(AUX_ENT): Adjust to use standard ELF AT_* macros.
	(AUX_ENTF): Ditto.  Remove always-0 middle argument.  Update all
	callers.
	(sim_open): Also pass AT_SECURE.
