Flex 4.6 AIR 19 iOS 9 Package fail on Flash Builder 4.7

[romainb18989113]

I keep getting this error.

ld: library not found for -lgcc_s.1

ld: library not found for -lSystem.B

Compilation failed while executing : ld64

Tried different settings inside the Platform Option file to package ANE, the ANE itself is packaged without error messages.

I got this error when I updated to xcode 7 including iOS 9 SDK to build my native extension. I updated Flash Builder to Air 19 released today but nothing changed.

There seems to be a solution following this thread.
