Changed "linux" target to "posix". Most of the changes are shared with
QuRT and with OSX. The Linux specific parts are in for i2c which uses
<linux/i2c.h> and <linux/i2c-dev.h>.

There is also a check for __PX4_LINUX in mavlink for a tty ioctl that is
not supported.

Seems that mavlink_receiver_linux.cpp inherited the history
from mavlink_receiver.cpp so updates went to it vs mavlink_receiver_nuttx.cpp

Two module.mk files used ifdef instead of ifeq.

Clang found the following:

which is doing fsbsf( bool )

Fixed to be:
