[patch, mips, elf.h] Fix elf.h values for MIPS archs.

[Steve Ellcey]

I have noticed that the values for some of the MIPS architecture levels listed
in elf/elf.h from glibc do not match the ones in include/elf/mips.h from
binutils.  Since the ones in binutils are what the GNU assembler and
linker and other tools are actually using, this patch is to change glibc
to match these values.

I am sending this to the libc-alpha mailing list instead of libc-ports since
elf/elf.h is in the main glibc area but this change would, of course, only
affect MIPS targets.

OK to checkin?
