So, currently fpc set's all branches to use arm4 mode

And C++ apps compiled could check what the system is using and use a
if to either call in arm4 or call in thumb mode. The strange thing is
that this is a bit arbitrary. There is nothing special about an OS
call, it's just a call like any other. I wonder where does the
compiler get the information of if the function is in arm4 or thumb
mode.
