This lets us remove the awkward ". ./redoconf.rc" line from zillions
of .od scripts, without paying the price of *always* including that
whole file every time default.do.sh is used.
- Linking shared libraries needs slightly different options.
- We were trying to detect mach_time.h but needed to detect
mach/mach_time.h instead.
While we're here, add a --disable-shared option to ./configure, which
is different from --enable-static. --disable-shared does not build
*new* share libraries, but doesn't pass -static to the linker
(apparently there is no static linking posible on MacOS).
Now we define HAS_POSIX=1 if it works, and to blank otherwise, to be
consistent with other rc scripts, but it doesn't abort if we can't find
timespec.
Meanwhile, slightly clarify the error message in rc.sh.

To test it out, try this:
./do -j10 build
cd docs/cookbook/c
redo -j10 test
It should detect all the compilers on your system and make three
separate builds for each one: normal, debug, and optimized. Then it
tries to run a test program under each one.
If there are windows cross compilers and you also have 'wine'
installed, it'll try running the test program under wine as well.
redoconf currently has no documentation other than the example program.
We'll fix that later.
