1.) Rename locore.s to locore.S (by repocopy), to be able to remove

    special-case make rule
2.) Cleanups, remove superfluous expicit rules, add -nostdlib to LDFLAGS,
    remove -X and -g, remove -g from CFLAGS
3.) Add BINDIR
4.) Build install the loader help file, add an empty help.sparc64
5.) Change the default configuration to only support booting from disk
6.) Get libofw.a from a path relative ${.OBJDIR}, not ${.CURDIR}
