Build firmware not working.

After I runned this (official) code:

# Get the Espruino source code
git clone https://github.com/espruino/Espruino.git
cd Espruino
# Download and set up the toolchain ('source' is important here)
source scripts/provision.sh ESP32
# Clean and rebuild
make clean && BOARD=ESP32 make

no espruino_esp32.bin was created.
The terminal last output is:

cc1: warning: unrecognized command line option '-Wno-expansion-to-defined'
make: *** wait: No child processes. Stop.

Please can you git pull and try again? I found a few build issues that I'm surprised haven't surfaced before, but it seems good now: https://travis-ci.org/espruino/Espruino

Ok thanks. The building worked. But after I flashed the firmware to the esp32 this message shows while booting:

there are some changes needed to make this work again

maybe this helps too
