Bug#702287: libm4ri: disables sse2 unconditionally

[Julian Taylor]

Package: libm4ri
Version: 20120613-2
Severity: normal

debian/rules passes --disable-sse2 to configure on all architectures.
amd64 is guaranteed to have sse2, so it can be enabled there, also don't
forget to enable it on kfreebsd amd64 too.


also please patch out this from configure.ac:

   case $host_cpu in i[[3456]]86*|x86_64*)
          AX_CPU_VENDOR()
          if test "x$ax_cv_cpu_vendor" = "xIntel"; then
             AX_EXT() # SSE2 is slower on the Opteron
          fi
   esac

this is certainly not true (any more?)
