Remove sizeof (long double) configure test.
There is a configure test for sizeof (long double) whose results aren't used anywhere. This patch removes that test. Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (sizeof_long_double): Remove configure test. * configure: Regenerated. * config.make.in (sizeof-long-double): Remove variable.
