Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH.

Browse Source 
This makes our naming scheme more closely match other systems and the
expectations of much third-party software.  MIPS builds which are little-endian
should require and exhibit no changes.  Big-endian TARGET_ARCHes must be
changed:
	From:		To:
	mipseb		mips
	mipsn32eb	mipsn32
	mips64eb	mips64

An entry has been added to UPDATING and some foot-shooting protection (complete
with warnings which should become errors in the near future) to the top-level
base system Makefile.

machines to maximize performance. (To disable malloc debugging, run
ln -s aj /etc/malloc.conf.)
20120328:
Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb
is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is
now spelled mips. This is to aid compatibility with third-party
software that expects this naming scheme in uname(3). Little-endian
settings are unchanged.
20120306:
Disable by default the option VFS_ALLOW_NONMPSAFE for all supported
platforms.
