If SBBSDIR is set, add $(SBBSDIR)/exec to rpath.
Always add the original output directory to rpath.

I'm not sure what the old LD_RUN_PATH stuff was trying to do, but
I think these are the bits that make it work.

Was overriding value, not appending.

It appears that setcap may cause $ORIGIN to stop working for some
unknown reason.

We don't build on SunOS anymore, and using LD_RUN_PATH sucks.
Also, it was badly out of date.

fix for commit 6e69eec1

For the SBBS binaries, set @executable_path and
@executable_path/../${LIBODIR} so they can all be in one dir, or
they can be in the build output dirs and still work.

For utilities, set to @executable_path and
@executable_path/../../${LIBODIR} for the same reason.

With this, we shouldn't need to fiddle with DYLD_LIBRARY_PATH

Remove the -E linker flag.
This should not be needed anymore, and isn't supported on macOS.

Have shared libraries include their full path.
This allows linked dylibs to work from where they were built, so
as long as you don't build the binaries on a CI machine, then try
to run them on a users machine (*cough*), it'll work out.

Use the correct rpath argument format on macOS.
It uses -rpath, not --rpath.

Prefer sdl2-config from the path, and only use the framework in
/Library/Frameworks if that doesn't exist... to that end, don't
copy the framework into the app anymore unless you're using it.

This should clean out the pipes.

Also fix last commit

Though we've had the auto-filtering feature for about a year now, with
expiration dates supported/added to every trash record, nothing was
removing the expired trash/filter items. Until now.

Check the size of your text/*.can files: if they're really big, this is
the solution.

Not yet building for Windows

Sysops will want to run this periodically (monthly?), e.g.
	trashman /sbbs/text/*.can

This build rule needed to be defined *after* objects.mk and rules.mk are
included.

Prevents crashes on modern FreeBSD systems that default to implicit
PROT_MAX in the JS code.
(It's possible that +wxneeded will be needed too.. still experimenting)

Search in both /usr/local (Homebrew) and /opt/local (MacPorts) for
libraries.

Also, have the name of GNU make be an in option in CI so we can use
the Apple-provided make.

It builds and appears to run... not actually tested.

By default, both NetBSD and OpenBSD will not allow pages to be mapped
both writable and executable.

On OpenBSD, if the filesystem is mounted with the wxallowed option,
this would work, and before v6.0, passing -z wxallowed to the linker
would allow it on a per-binary basis.  However, since this is not
the default, and since the JS engine can use mprotect() to switch
between RW and RX, I've decided to enable this instead.  This will
slow things down, but it will work "out of the box".

For NetBSD, the situation is different, you can't switch between
RW and RX using mprotect()... instead, you need to use mremap() to
get a separate mapping for each set of perms.  This does *not*
appear to be present in the 1.8.5 source, so we can't do the same
fix as OpenBSD.  Instead, NetBSD allows paxctl to add an elf note
indicating that RWX is needed, and it "just works" (by default).

Fixes OpenBSD build issue.

... weird this wasn't required before now.

Removed obsolete DSTSEDIT target.
