Non-recursive path to local module copy (in Xcode 6.1.1)

The libFLAC is also giving us hard time.

When add here at least for plug-ins I get the FLT_MAX undeclared identifier and also assert is no longer available.
(workaround for assert is to use jassert or encapsulate it somehow).

Workaround for FLT_MAX is to set within the Modules settings:
JUCE_USE_FLAC to Disabled
