building on RPI 3: undefined reference to symbol 'pthread_getspecific@@GLIBC_2.4'

Hi,

On my rpi 3 I run into issues when building upm (after building and installing rmaa).

pi@mark2:~/upm/build $ make

I tried cmake with several options so far (none worked obviously ^^):
cmake ..
cmake .. -DBUILDSWIGNODE=OFF
cmake .. -DBUILDSWIGNODE=OFF -DBUILDARCH=arm -DCMAKE_C_FLAGS='-pthread'

I build rmaa without nodejs stuff as I ran into issues there and I do not need it.

Any tips on how to resolve this issue?

Kind regards,
Chris
