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! ;-)

     1 GCC trunk now has multiple internal headers directories, one

     2 containing the self-contained GCC-provided headers and one containing

     3 the <limits.h> (not self-contained but including libc's <limits.h> or

     4 a fixed version thereof) and the fixed headers; more such directories

     5 may be added in future.

     6 

     7 When glibc uses -nostdinc, it needs to use -isystem options for all

     8 these internal directories.  This patch teaches it about the

     9 include-fixed directory (and is harmless with old GCC versions without

    10 that directory).

    14 	* configure.in: Also pass -isystem option for GCC's include-fixed

    15 	directory.

    16 	* configure: Regenerate.
