Subject: [PATCH] Allow for building the MIPS DSPr2 extensions if the host is
 mips-* as well as mipsel-*.  The DSPr2 extensions are little endian, so we
 still have to check that the compiler defines __MIPSEL__ before enabling
 them.  This paves the way for supporting big-endian MIPS, and in the near
 term, it allows the SIMD extensions to be built with Sourcery CodeBench.
