No, you are mixing several issue in one big bowl ;)

As you seem to be using rtems-CVS/4.7, this file (and many others) has
been moved to rtems/ (<rtems/rtems.h>) in rtems-4.7.

I.e. this probably is a source code bug.

When using an installed rtems-4.7 you should not have to specify any
-isystem or -I options except for the BSP headers.

-I is correct. These dependencies also are.
