Reverting to a snapshot from 20000906, there was no relocation information
printed by objdump for the call:

 20c:   e8 5f 1b dd     b,l 0 <reset_used_flags>,rp
 210:   08 00 02 40     nop

A similar recursive call in copy_rtx_if_shared has the relocation info:

458:   e8 40 00 00     b,l 460 <copy_rtx_if_shared+0x460>,rp
                       458: R_PCREL_CALL       copy_rtx_if_shared+0x40000000
45c:   08 00 02 40     nop

Checking the new linked version of cc1, the code looks ok for the call to
reset_used_flags.  So, it appears that the R_PCREL_CALL relocation was added
incorrectly by the new version of gas to a "local" branch with its offset
setup by the assembler.
