Version: 0.6.1-5

rakarrack fails to cross build from source, because it detects sse
support from the build machine and passes e.g. -msse2 to an armhf
compiler when building on amd64. Disabling autodetection of sse is
tricky. The only way I found was exporting a non-empty SSE variable.
After doing so, it is globally disabled, so to retain sse2 support where
we want it, we must explicitly --enable-sse2 it. Please consider
applying the attached patch.
