uClibc: Add uClibc patch to fix MIPS64/n64 interpreter 

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

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.
