Simon Hausmann 9b3b33b110 Fix linking warnings on OS X with qmlimportscanner
The linker complains that some symbols were compiled with different visibility
settings when linking host_build tools such as the import scanner. As it turns
out, we do CONFIG += hide_symbols for static libraries (such as bootstrap or
qmldevtools) but naturally not for the final program source code. It appears
symbol visibility is not of importance for static libraries in host builds (as
opposed to static libraries later linked into shared libraries), therefore this
patch removes that.
