Subject: [PATCH] lib/neardal.h: fix build with gcc 10

Define neardal_output_cb as extern to avoid the following build failure
with gcc 10 (which defaults to -fno-common):

/srv/storage/autobuild/run/instance-2/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: ./.libs/neardal_adapter.o:(.bss+0x0): multiple definition of `neardal_output_cb'; ./.libs/neardal.o:(.bss+0x68): first defined here

Fixes:
