Setting MGOS_DEBUG_UART to 1 breaks rpc-uart

Hello,

We are using mos 2.15.0.

If trivial firmware is compiled with mos build --platform esp8266 --local --clean --build-var MGOS_DEBUG_UART:1 then RPC over UART (eg. mos config-get) doesn’t work (timeouts).

AFAIK this wasn’t case in 2.14.0.

Is it a bug in mos? I think MGOS_DEBUG_UART shouldn’t influence non-debug functionality.

Best regards
