[Patch] Remove extra bits/endian.h file for MIPS

[Steve Ellcey <sellcey at imgtec dot com>]

Here is my proposed patch to remove the extra bits/endian.h file
for MIPS.  I removed the linux specific one and used the generic
one after fixing the comment.  My earlier patches already changed the #if's
to #ifdef's in that file.  This means that for linux we will now check
__MIPSEB/__MIPSEL instead of __MIPSEB__/__MIPSEL__ but that seem reasonable
since we are setting __BYTE_ORDER (with no trailing underscores).
Both versions of the MIPS macros are set by GCC.

I did not add any error checking to verify that one and only one 
of __MIPSEB/__MIPSEL are set.  The compiler will only set one of 
these and if the user does something weird with -D/-U flags then
I think they are on their own.  There are lots of places in
glibc where we assume the compiler defined macros are in a rational
state without explicitly checking them.

Tested with mips-mti-linux-gnu.  Ok for checkin?
