The issue appear with gdb 7.11.1 only, that's due to bundled gnulib version has
been updated.
We didn't see this issue in the autobuilders since gdb 7.11.1 is not tested (not
the default Kconfig choice)

Anyway, I tested your proposal with gdb 7.11.1 and it working well :)

I'll resend the patch in a moment.

Best regards,
Romain
