getloadavg, getopt: fix commentary re configure.in Autoconf is deprecating the name 'configure.in', so change it to to the new name 'configure.ac' in a couple of places. * lib/getloadavg.c: configure.in -> configure.ac, in comment. * m4/getopt.m4 (gl_GETOPT_IFELSE, gl_GETOPT_SUBSTITUTE_HEADER) (gl_PREREQ_GETOPT): Remove obsolete commentary re Emacs configure.in. Emacs has renamed it to configure.ac, and it no longer refers to these macros anyway.
