arch/mips: add experimental mips64 samples

Both toolchains were tested to successfully:
- _build_ busybox, giving respectively an n32 and an n64 binary
although it has not been run-tested.
- build linux-2.6.36-rc3 for Loongson, giving an n64 vmlinux
(which is expected, due to the way the kernel is built),
and the kernel properly boots!

Credits are due to Julien MOUTHINO (julm on freenode#uClibc) for
testing that the kernel boots on his hardware! Cheers! ;-)

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch
     5 Set the default behavior on alpha to use -mieee since the large majority of
     6 time we want this (bad/weird things can happen with packages built without
     7 -mieee).
     8 
     9 To satisfy those people who may not want -mieee forced on them all the time,
    10 we also provide -mno-ieee.
