Strictly POSIX-compliant shells (like dash) do not allow sourcing files in the present directory without "./". The script really should not know or care about what directory the passed files are in, so now we add a jam grist to make the passed paths absolute. Fixes the build on all systems where /bin/sh is dash or a similarly POSIX-compliant-no-extensions shell (i.e. virtually all Linux.)
