That's incorrect.  R_ARM_PLT32 is treated the same as R_ARM_ABS32 but
is a 'hint' that a PLT entry should be used.

Dave (Murphy), would you mind describing your testcase in more detail. 
Also, you said you'd applied a patch to GCC but did not describe what
it was.  And you never told us what version of binutils you were using.

The concept of a PLT32 relocation overflowing is a little odd.
