I had contemplated injecting the -b switch via
# any custom options you might want to pass to zic while installing data files
-ZIC_OPTIONS =
+ZIC_OPTIONS = -b slim
which would allow overriding it by defining the ZIC_OPTIONS macro.
Does that seem appropriate? I didn't do it because I worried about
interference with existing uses of ZIC_OPTIONS ... but who knows
whether there are any.
BTW, building with old versions of zic is not guaranteed to work anyway.
They do tend to wait a year or two before they start to use new zic
features in the timezone data files, but they don't wait indefinitely.
