configure.in: Replace old AC_PROG_CC hack with new one.

* configure.in: Replace old AC_PROG_CC hack with new one.
	Define toplevel_srcdir in terms of srcdir, not top_srcdir (there
	are no subdirectory output files, so this is fine).  Change prereq
	to autoconf 2.59.
	* aclocal.m4: Include ../config/no-executables.m4.
	* configure: Regenerate with autoconf 2.59.

# copied from autoconf 2.12, but does not call AC_PROG_CC_WORKS. We
# are probably using a cross compiler, which will not be able to fully
# link an executable. This should really be fixed in autoconf
