I think I fixed this (revision 106305 on the trunk), please check.
For the record: I decided that loading uni-bidi in advance is not a
good idea, as proper functioning of character property tables needed
by bidi.c depends on many other *.el files that are normally loaded
before uni-bidi. There be dragons there. So instead, I disabled bidi
reordering for as long as purify-flag is non-nil; I hope this is TRT
for all supported configurations, including CANNOT_DUMP.
