I don't think I'm breaking big endian support with my patch since if
you have the ld command:

   OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradlittlemips")

you say to the linker that your default endian is "big", please see:

   info -f /usr/local/mipsel/info/ld.info -n "Format Commands"

So if you do not specify "-EB" nor "-EL" the linker will use default
(big endian in the above example).

The following patch also fixes examples compilations:
