    Fix submake dependency bug with .h files
    
    * src/Makefile.in ($(libsrc)/make-docfile$(EXEEXT)):
    Depend on $(lib)/libgnu.a, so that we build $(lib)/*/*.h
    before the submake in $(libsrc) would spin off a subsubmake
    for $(lib) in parallel with our submake for $(lib) (Bug#20894).
