This isn't quite finished yet, there are still some unresolved problems
with ospeed and the sgtty.h (non-posix) terminal interface. Mostly
this only causes problems with src/games.
The other tools and libraries (libform,libpanel,libmenu) will come
shortly but are seperate.
Beware, there be dragons here! (The build will be broken for a short
while)
the highly non-recommended option ALLOW_BDEV_ACCESS is used.
(bdev access is evil because you don't get write errors reported.)
Kill si_bsize_best before it kills Matt :-)
Use the specfs routines rather having cloned copies in devfs.

statement to put the rcsid into the .comment section. This allows
the comments (ie:version id's of compiler, headers, source, etc) to be
stripped out with the standard tools (strip/objcopy). SVR4 has a
tool called 'mcs' (manipulate comment section) which allows you to
add/remove/compact strings. Removing duplicate strings helps a lot
if the headers generate them.
Using __attribute__((section(".comment"))) would probably also work,
but that still leaves the RCSID occupying C name space somewhere.
`opaque', fix reversed description of `nodump', and don't use
`nodump' as an example of adding a `no' prefix since the double
negative would be confusing (it's still confusing -- the implicitly
documented `nonodump' flag doesn't exist).)
PT_INTERP program header entry, to ensure that gdb always finds
the right dynamic linker.
Use obj->relocbase to simplify a few calculations where appropriate.
loaded separately by dlopen that have global symbols with identical
names. Viewing each dlopened object as a DAG which is linked by its
DT_NEEDED entries in the dynamic table, the search order is as
follows:
* If the referencing object was linked with -Bsymbolic, search it
internally.
* Search all dlopened DAGs containing the referencing object.
* Search all objects loaded at program start up.
* Search all objects which were dlopened() using the RTLD_GLOBAL
flag (which is now supported too).
The search terminates as soon as a strong definition is found.
Lacking that, the first weak definition is used.
These rules match those of Solaris, as best I could determine them
from its vague manual pages and the results of experiments I performed.

Also return "1" rather than "-1". According to bde: -1 is unrepresentable.
Exit statuses must be >= 0 and <= 255, at least if chars are 8 bits and
shorts are 16 bits. This seems to only be documented indirectly in exit.2
by referring to wait.2. WEXITSTATUS() throws away all except the low 8 bits
of the status returned by _exit(), and the kernel actually only stores 8
bits of it (if chars are 8 bits, etc.), so wait() can't return any more bits.
