[svn-r19696] Bug 2008 - IBM Power6 Linux uses special conversion algorithms to convert some values from long
double to (unsigned) long and from (unsigned) long to long double. I added tests in configure.in to detect these algorithms. Before I can figure out them, I disable the tests in dt_arith.c. There are property changes to tools/misc, config, and Makefile.am when I brought the fix from 1.8. Tested on jam, heiwa, amani, IBM Power6 Linux machine in Holland (huygens.sara.nl).
