RFCOMM support for bluetooth devices

[covar2077]

Hello
I'm trying to recompile this kernel in order to enable RFCOMM support for Bluetooth Arsenal in nethunter apk.
I get a bunch of errors. One of these is this:
arch/arm64/Makefile:55: *** /home/arter97/arm32-gcc/bin/arm-eabi-gcc not found

Could you please give instructions how to recompile your kernel??
