if this does what I think it does, it won't work on OSX either, debug
libraries are inside the framework bundle, so it's named the same
either way.

The framework contains:

  Foo.framework/Versions/Current/Headers
  Foo.framework/Versions/Current/Headers/foo.h
  Foo.framework/Versions/Current/Foo
  Foo.framework/Versions/Current/Foo_debug
  Foo.framework/Versions/Current/Foo_profile

where "Foo", "Foo_debug", and "Foo_profile" are the normal, debug, and
profiling versions of the framework, respectively.

If you were to just turn all "-framework Foo"'s into "-framework
Foo_debug"'s, it wouldn't work.  You instead set the environment
variable DYLD_IMAGE_SUFFIX to "_debug".  If dyld can't find the
framework with _debug at the end, it falls back to the non-debug one.
