Perhaps you could use the *synthetic_symtab hook I've added recently for that.
In addition to all those synthetic foo@plt symbols add one symbol for the
beginning of .plt and make sure it will be sorted before the actual
_PROCEDURE_LINKAGE_TABLE_ symbol.
It can be _PROCEDURE_LINKAGE_TABLE_ as well, would need to study
compare_symbols how to trick it to have this one first.
This would not help just the targets which have this symbol, but
others as well.
ATM e.g. on i386 I get:
Disassembly of section .plt:

080488a0 <__fpending@plt-0x10>:
 80488a0:       ff 35 e8 b0 04 08       pushl  0x804b0e8
 80488a6:       ff 25 ec b0 04 08       jmp    *0x804b0ec
 80488ac:       00 00                   add    %al,(%eax)
        ...

080488b0 <__fpending@plt>:
 80488b0:       ff 25 f0 b0 04 08       jmp    *0x804b0f0
 80488b6:       68 00 00 00 00          push   $0x0
 80488bb:       e9 e0 ff ff ff          jmp    80488a0 <__fpending@plt-0x10>

080488c0 <__overflow@plt>:
 80488c0:       ff 25 f4 b0 04 08       jmp    *0x804b0f4
 80488c6:       68 08 00 00 00          push   $0x8
 80488cb:       e9 d0 ff ff ff          jmp    80488a0 <__fpending@plt-0x10>

__fpending@plt-0x10 is certainly not pretty, .plt or
_PROCEDURE_LINKAGE_TABLE_ would be far better.
