Skip dependency detection if library is fully precompiled
cc0e4c1 
Precompiled bits of a library should not depend on any link time dependency (we cannot assure ABI stability).
Fixes arduino/ArduinoCore-mbed#119

update. I tried the "hello_world" example on Portenta M7 Core. The code compiles ok but the crashes when run. TF Lite 2.4.0 Alpha , mbedOS core 1.3.1. The red LED flashes 4 long blinks and 4 short blinks

@mbanzi the crash on Portenta is due to the example trying to analogWrite() on LED_BUILTIN which is not PWM capable. mbed core crashes in this case instead than falling back to digitalWrite() due to an assert in mbed itself.
I'm wondering which is the best way to proceed, if "masking" the assert or changing the example for Portenta

Thanks for pointing that out. :) In the other Arduino cores trying to PWM a non PWM pin we just fall back to digitalWrite
is this something we can/want to do with Portenta as well? We can always modify the example adding some ifdef for Portenta
