Force siphash24 hash algorithm when cross-compiling

When cross-compiling, the hash function is forced to be FNV because the
configure script defines `HAVE_ALIGNED_REQUIRED` which is then used by
pyhash.h to change the default to FNV (see conda-forge#718)

This commit fixes the issue by specifying siphash24 to the configure
script when cross-compiling.
