it looks like MJ5 is using a hardware include for an older version of
the tiny (line212 of microjet5.xml)
ap.CFLAGS +=  -DFBW -DAP -DCONFIG=\"tiny.h\" -DLED -DTIME_LED=1

replace that -DCONFIG=\"tiny.h\" with something compatible with your
version of the tiny
( maybe   -DCONFIG=\"tiny_2_1.h\" )

you can set what do you want on each UART ( GPS, telemetry) by
changing those lines your airframe file
( from microjet5.xml)

ap.CFLAGS += -DDOWNLINK -DUSE_UART0 -DDOWNLINK_TRANSPORT=PprzTransport
-DDOWNLINK_FBW_DEVICE=Uart0 -DDOWNLINK_AP_DEVICE=Uart0
-DPPRZ_UART=Uart0 -DDATALINK=PPRZ -DUART0_BAUD=B57600
ap.srcs += downlink.c $(SRC_ARCH)/uart_hw.c datalink.c pprz_transport.c

ap.CFLAGS += -DGPS -DUBX -DUSE_UART1 -DGPS_LINK=Uart1 -DUART1_BAUD=B19200
ap.srcs += gps_ubx.c gps.c


here, you have telemetry/datalink on UART0 at 57600 and GPS on UART1 at 19200
