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.

GCC 4.8 and higher implement 16 byte static data alignment on 64-bit.
This means that the 24-byte param_info_s variables are 16 byte aligned
by GCC and that messes up the assumption that the address of the second
parameter is at ¶m[0]+sizeof(param[0]).
When compiled with clang it is true, with gcc is is not true.
See https://llvm.org/bugs/show_bug.cgi?format=multiple&id=18006
The fix is needed for GCC >=4.8 only. Clang works fine without this.
Added __attribute__((aligned(16))) to first member of param_info_s.
