Well, I got the switch that triggers it: HAVE_LD_EH_FRAME_HDR

If this Macro was defined, the crtbegin code cannot handle the
situation I described in the bug report.  Without it can handle the
situation quite sane.  This is the case with _all_ compilers since 3.2
release.  (I haven't an older one at hand to test.)

Obviously this switched is on if you used binutils 2.12.x.x.x at
configure time as they support this feature, but 2.11.x.x.x do not and
such it is turned off there.  So it is perfectly clear now, why you
couldn't reproduce the problem.

This means the problem obviously is in the crtstuff code that handles
eh_frame_hdr stuff.

So we need some binutils gurus here.
