[Buildroot] [PATCH v2] 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.

The patch has been committed upstream:
http://git.uclibc.org/uClibc/commit/?id=603af30d6992e94ac30a66b953264076f4f2fd71

Changes since v1:
- Adjust to new uclibc paths
- Update patch to be compatible with make-3.80 and match the one
actually committed upstream

+Subject: 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.
