build shared versions of libraries building defaults to off until clang is updated. current clang does not handle -shared, necessary to change the ld invocation to build shared libraries properly. a new clang should be installed and MKPIC defaults to no unless the newer clang is detected. changes: . mainly small imports of a Makefile or two and small fixes (turning things back on that were turned off in Makefiles) . e.g.: dynamic librefuse now depends on dynamic libpuffs, so libpuffs has to be built dynamically too and a make dependency barrier is needed in lib/Makefile . all library objects now have a PIC (for .so) and non-PIC version, so everything is built twice. . generate PIC versions of the compat (un-RENAMEd) jump files, include function type annotation in generated assembly . build progs with -static by default for now . also build ld.elf_so . also import NetBSD ldd
