[tlbuild] asy on Macintosh

[John Bowman]

Hi Mojca,
It's good to know that there is a new gc release (and that the official
source has moved, with a 8.0.4 released just 27 days ago) and that it
compiles on the Mac.
I will make a new release with these changes later today. It will also
include a fix to an asy bug (broken soccerball example) that needs to fixed
across all platforms.
What do we do about -lgccpp? Is that still needed for some MacOSX platforms
and if so is there a way to detect which ones?

Thanks for the feedback,

-- John
