The Eagle HW platform contains both a Krait (ARMv4hf compatible) cpu
cluster and a Hexagon DSP running QuRT.
These changes support the PX4 build for Eagle.

Moved nuttx specific make rules to files in makefiles/nuttx.
All target specific makefiles are in their target sub directories.
To minimize file duplication, targets that share rules include a
common file. For example the posix and posix-arm targets both use
makefiles/posix/posix_elf.mk

QuRT doesn't support unlink and does not provide getpid().
The DSPAL layer provides access to usleep so an implementation is
no longer needed.

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.
