The problem is in fail, and it seems that the 'run rp2gen to make
fcon.h from fcon.rpc2' rule is not getting picked up (since 'make
fcon.h' does nothing) or run (since 'make ft.h' says that it doesn't
know how to make ft.h).

I don't have any bright ideas of how to make this work with bmake, so
noting in INSTALL that one needs gmake is probably the best bet.

Patch to update INSTALL, also noting that GNU readline is needed for filcon:

+While RPC2 does not need GNU readline, if readline is present the
+'filcon' program will be built.
