I believe it's already structured that way:

$ find ~/_Inline/ -type f
/home/branden/_Inline/config-x86_64-linux-gnu-thread-multi-5.032001
/home/branden/_Inline/lib/auto/gropdf_1c9b/gropdf_1c9b.inl
/home/branden/_Inline/lib/auto/gropdf_1c9b/gropdf_1c9b.so
/home/branden/_Inline/.lock

This much is not the case.  Apart from gnulib, with which many people
are familiar (and which supports no DSO configuration TTBOMK), the groff
build produces up to four libraries--libgroff, libdriver, libbib, and
libxutil--but all are static (".a" files).
