permanently disable opendir.o until its link bugs (on ELF platforms

only?) are sorted out.  speculation (based on some analysis by simonb)
is that it's because fts calls _opendir2 directly, which forces both
the libhack and the libc versions of opendir.o to be linked in.
in any case, there's space saves to be had elsewhere...
