BR2_ARCH_IS_64 is set for mips64/mips64el even when the n32 ABI is
used, so openblas was built with BINARY=64. Its build system then
passes -mabi=64, which conflicts with the n32 sysroot:

  gnu/stubs.h:35:11: fatal error: gnu/stubs-n64_hard.h: No such file
  or directory

For openblas, BINARY refers to the pointer size rather than to the
architecture, and n32 uses 32-bit pointers, so BINARY=32 is correct
there.
