This cannot be implemented as you wish. The ability to compile in C mode when
CC="g++" is done through a variable NO_CXX that has to be added to the compiler
flags. But modifying compiler flags can, in a Makefile.am, only be done on a
per-program or per-library basis, not on a per-compilation-unit basis.

So, you have to add $(NO_CXX) to the compilation flags for your library 
yourself.

In theory, one could add a 'traditional-c' flag to the module description, let
gnulib-tool see if one of the modules of the library has this flag set, and add
$(NO_CXX) to the compiler flags of the library. But that would be a lot of code
to develop, and given that you have an easy one-liner workaround, I don't see
much point in having this feature in gnulib proper.
