[Ada] Minor tweaks to gnat.dg testsuite

[Eric Botcazou <ebotcazou at adacore dot com>]

The gnat.dg testsuite contains a dozen of spurious failures on 64-bit Windows 
because of a couple of issues: the target is P64 and some patterns in filename 
give rise to warning at link time.

Fixed thusly, applied to all active branches.


2018-02-16  Eric Botcazou  <ebotcazou@adacore.com>
