cln: use templates for {int,float}param.h for cross
When cross building the configure script hangs or at least takes
insane amounts of time for some architectures to create the values
for the header files include/cln/{int,float}param.h
Since we know our architectures and the sizes of their integer
and floating point values, we can just as well create the files
from templates using $XBPS_TARGET_WORDSIZE and $XBPS_TARGET_ENDIAN.
