#1735: Pmc2c line numbering confuses gdb

----------------------+-----------------------------------------------------
Using the default configuration, gdb is unable to step through vtables,
giving messages such as:
{{{
0x00007ffff7a90ae4 in Parrot_OpLib_init_pmc (
interp=0x60a080, _self=0x789770,
name_pmc=0x7892d0)
from /home/pitr/dev/parrot/dynop_mapping/blib/lib/libparrot.so.2.6.0
(gdb) n
Single stepping until exit from function Parrot_OpLib_init_pmc,
which has no line number information.
Parrot_pmc_new_init (interp=0x60a080, base_type=37,
init=0x7892d0) at src/pmc.c:551
551 return pmc;
}}}
This is a significant drag because much Parrot functionality is inside
vtables.
Reconfiguring with --no-line-directives, which disables line directive
generation from tools such as pmc2c, the vtables become steppable.
