See Joel's email. To build a correct compiler toolchain for RTEMS, you
have to modify binutils and gcc.

RTEMS needs some customization in the compiler to add the -rtems target. Since support has never been added for v8, there will not be any such compiler support available yet. So the first step has to look at adding that support:
