  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:
