Something like this should be needed for current kernel to make
autoconf happy ...

[Bradley D. LaRonde]

For autoconf?  Why need to ask the kernel?  Aren't there other very simple
ways of determining build endianness in userspace?

Brad

There is - But autoconf in the current version is broken and needs this
to gather the endianess - As we currently have to live with it this is
a 2.4 issue - 2.5 should fix this and remove endianess from
/proc/cpuinfo.

I understand, thanks for the explanation.  So the patch should only go in
the 2.4 branch?

Brad

Ah - Here is the responsible autoconf bit from config.guess:

   mips:Linux:*:*)
       case `sed -n '/^byte/s/^.*: \(.*\) endian/\1/p' < /proc/cpuinfo` in
         big)    echo mips-unknown-linux-gnu && exit 0 ;;
         little) echo mipsel-unknown-linux-gnu && exit 0 ;;
       esac

This has already been discussed and probably even fixed in autoconf
upstream ...
