debian/rules (PACKNAME, MAKEVARS): New variables, to reduce redundancy. $(PACKNAME) replaces libofx2c2a. $(MAKEVARS) is prefixed on all invocations of make. Specify LIBOFX_DTD_DIR on make invocations. (install): No longer move files into correct location, since the new make variables just install them properly the first time. (Closes: #343722)
