* 32-bit SPARC binutils do not generate them,
* and now the 64-bit SPARC binutils have stopped
* generating them too.
*
* So, to provide binary compatibility, we will
* check the first entry, if it is reserved it
* should not be of the type JMP_SLOT. If it
* is JMP_SLOT, then the 4 reserved entries were
* not generated and our index is 4 entries too far.
