uClibc: Add uClibc patch to fix MIPS64/n64 interpreter

Browse Source 
uClibc picks the wrong interpreter for MIPS64/n64.
This patch fixes this problem by checking the selected
MIPS ABI instead of the MIPS variant.

This patch was sent upstream:

Subject: [PATCH uClibc] Rules.mak: MIPS64: Select correct interpreter
gcc (eg 4.7.3) hardcodes the MIPS64 interpreters like this:
(see gcc/config/linux.h and gcc/config/mips/linux64.h)
o32: UCLIBC_DYNAMIC_LINKER "/lib/ld-uClibc.so.0"
n32: UCLIBC_DYNAMIC_LINKERN32 "/lib32/ld-uClibc.so.0"
n64: UCLIBC_DYNAMIC_LINKER64 "/lib/ld64-uClibc.so.0"
The existing check for MIPS64 in uClibc is wrong because it does
not respect the selected ABI
We fix this by explicitely checking the selected ABI instead of the
selected MIPS variant.
