Should be, but i have never done it myself. However, i would actually
recommend using the synthetic target on Linux.

Redboot does not use the kernel.

I would suggest you use the kernel test cases. These are good tests to
see if your changes have broken anything. 

Try doing:

ecosconfig new pc_rltk8139
edit ecos.ecc and change CYG_HAL_STARTUP to floppy
ecosconfig tree
make -s tests

Once you have fixed all the compiler error you can run the test cases
in install/tests/kernel/current.
