The toolchain_* files are target OS specific so they were moved to
the target OS subdir.
The gcc_version.* files are only cleared once per make instantiation so
a build that creates multiple HW targets will try to link with an
incompatible .o file (i.e. x86 build linking ARM .o). I created
posix-arm as a separate target to fix this problem.

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.

The getopt command uses global variables and is not thread safe.
Created a minimal px4_getopt version that supports options with
or without an arg, and random placement of options on the command line.
This version modifies the order of the args in argv as does the
POSIX version of getopt.
This assumes that argv[0] is the program name. Nuttx may not support
that properly in task_spawn.

Moved the NuttX specific board files to makefiles/nuttx and added
a makfiles/linux directory with sample config and board files.
Created a makefiles/toolchain_native.mk file for building for Linux
with the native system compiler. GCC or clang can be used by setting
a flag in the file.
The Linux build creates an archive file and will build the tasks as
threads. Other code changes are required to support both task based
and thread based builds.
The NuttX source should not be required for the Linux build. The
target OS (NuttX or Linux) is selected by commenting out the desired
line in setup.mk
