maint: avoid empty lines in recipes

AIX 7.2 ‘make’ complains about recipe lines that are empty after
macro expansion, and I suppose there’s a good chance some
non-POSIX ‘make’ would prohibit them.  Rework macros so
that we can avoid them.
* gnulib-tool (func_emit_lib_Makefile_am)
(func_emit_lib_Makefile_am): Support @!NMD@ too.
* modules/gen-header (@gl_V_at): New macro.
* modules/alloca-opt, modules/argz, modules/assert-h:
* modules/byteswap, modules/configmake, modules/ctype:
* modules/dirent, modules/errno, modules/execinfo, modules/fcntl-h:
* modules/float, modules/fnmatch-h, modules/getopt-posix:
* modules/glob-h, modules/iconv-h, modules/ieee754-h:
