vxworks header files require that the compiler define CPU.  So verify
that your gcc is defining CPU.  Try creating a file tmp.c in the gcc
build dir that just contains "CPU" and compile it with "./xgcc -B./ -E
tmp.c".  Then check that the vxworks header files support the CPU
value that gcc is defining.  The gcc CPU value should be coming from
gcc/config/rs6000/vxworks in the CPP_SPEC definition.  The error
message points at the place in the vxworks header files where it is
checking CPU.
