One of the reasons that gnulib moved towards assuming <config.h> is that
it makes for shorter command lines in make output, and it is easier to
write maintainer-check rules that ensure every .c includes <config.h> as
the first line (a necessity if gnulib replaces any system header).  In the
early days of autoconf, it was sufficient to just list lots of -D...
options on the command line, but these days, gnulib defines so many macros
that it is feasible to exceed command line limits on some platforms if you
do not lump them all into a config.h.

I think it will be easier for you to provide a stub lib/config.h than to
try and restore all the sed invocations into gnulib-tool to convert to
your custom name at checkout, not to mention that gnulib-tool is already
slow enough as it is.
