progname: also set global program_invocation_name, when possible. Before this change, a libtool-enabled program that calls glibc's error function would report the program name as "/abs/dir/.libs/lt-program_name" rather than the desired program_name. * modules/progname (configure.ac): Check for a declaration of program_invocation_name. * lib/progname.c: Include <errno.h>. (set_program_name) [HAVE_DECL_PROGRAM_INVOCATION_NAME]: Set program_invocation_name.
