 * The generated assembler does the usual trick (relative
 * branch-and-link to next instruction) to get a copy of the
 * instruction ptr. Instead of branching to an explicit zero offset,
 * it branches to the symbol `__eabi' --- which is expected to be
 * undefined and thus zero (if it is defined as non-zero, things will
 * be interesting --- as in the Chinese curse). To shut up the VxWorks
 * linker, we define `__eabi' as zero.
 *
 * This is just a work around. It's really Wind River's GCC's code
 * generator that should be fixed.
