perf: append endianness argument to ld when building for MIPS
PATCH v2 1/1 perf: append endianness argument to ld when building for MIPS
We need to pass an argument to ld for setting the endianness when building it for MIPS architecture, otherwise the default one will always be used (which is big endian) and the compilation for little endian will always fail showing an error like this one:
LD foo.o
mips-linux-gnu-ld: foo.o: compiled for a little endian system and target is big endian
---
Changes v1 -> v2:
- Simplify the logic of the ifeq block.
