[Freeswitch-users] Cross compiling freeswitch for raspberry pi

Its already some time ago (March 2013) when we built Freeswitch with a
fresh compile from git on Rapsberry Pi.
But it just worked right of of the box, after having all dependend
libraries installed on Raspbian. It takes a couple of hours though until
./configure finshed and to see that a library was missing. So every time
it took some hours again to solve the next problem with missing
dependencies. But finally it worked.
And I cannot guarantee that every module is working, we just used just
the minimum of modules to make it working as a SBC and to register phones.
I think it makes sense to write down all the needed installation steps
for compiling Freeswitch on RPi in a seperate wiki chapter.
I did some basic steps here:
