log-ieee: Work around test failure on NetBSD 5.1 and Solaris 11. * m4/log-ieee.m4: New file. * m4/log.m4 (gl_FUNC_LOG): If gl_FUNC_LOG_IEEE is present, test whether log works with a negative argument. Replace it if not. * lib/log.c (log): For negative arguments, return NaN. * modules/log-ieee (Files): Add m4/log-ieee.m4. (configure.ac): Invoke gl_FUNC_LOG_IEEE. * doc/posix-functions/log.texi: Mention the log-ieee module.
