The current template mistakenly treats a MACOSX_DEPLOYMENT_TARGET value
of "10.10" as "10.1" followed by junk. Thinking that the build is
targeting 10.1 Puma instead of 10.10 Yosemite, it tells the linker to
ignore undefined symbols instead of dynamically resolving them. This can
cause runtime crashes* and will affect subsequent versions of OS X.
