On macOS there is some warnings about object that has no symbols in it, this is needed to be fixed to make building more clean and clear.

example of build log :

[ 94%] Linking CXX static library libretdec-bin2llvmir.a
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libretdec-bin2llvmir.a(idioms_borland.cpp.o) has no symbols

Fix compiler warning (unused variable 'ai')

Unify build visibility for all projects to avoid warnings "direct access in function: * from file: * to global weak symbol".

PS: used same function 'append_if' from LLVM Project CMakeLists.txt file

This will fix avast#331

After those, there will be no warnings at all on macOS compile time.
