Well, for any OS version, there may be more than one Xcode version that 
can be installed, and a given Xcode version sometimes includes more than 
one toolchain version.  In general, the way I set up the VMs is to have 
the latest Xcode (with command-line tools) for the given OS, and whatever 
toolchain it gets by default via command-line invocation.

This time I just attached the whole output of the run, instead of 
selectively copying and pasting.  The main things that might not be 
obvious are:

1) The script supplies the -s option, to exclude most of the uninteresting 
chatter while still showing warnings and errors.  That's why I tweaked 
SConstruct to avoid suppressing the "This system is..." message in -s 
mode.

2) Some compilers emit a huge pile of warnings over some structure 
initialization issue.  That's been a known problem for ages, but there are 
so many of these messages that I included a grep filter to get rid of 
them.  But it doesn't filter out messages on preceding lines specifying 
the error location, so you may sometimes see stuff like:

        MacSLS: rtcm3_json.c: In function 'json_rtcm3_read':
        MacSLS: rtcm2_json.c: In function 'json_rtcm2_read':

Those should just be ignored.

These runs are build-only, since the regression tests aren't needed to 
chase these sorts of problems.
