Proposed patch

I managed to get a working qemu setup without much efforts using Buildroot,=
 and
I can reproduce the issue.  Although if there is a ready-to-use Ubuntu imag=
e I
can use, I'd be happy to use it (I just don't want to go through the troubl=
e of
installing the distro in qemu with the installer).

See the attached patch, it does fix the issue for me.

However, the inferior always hits this when running:

    Program received signal SIGSEGV, Segmentation fault.
    0x000003ffac312c6c in _dl_debug_initialize () from /lib/ld64.so.1

... and that was happening prior to my patches, and in GDB 10.  I guess you
don't see it?
