gstreamer1: fix compile for microblaze and xtensa architectures

Browse Source 
Fix unaligned access support detection introduced to gstreamer
by commit 'gstconfig.h: Detect unaligned access support at compile-time' ([1])
by assuming no unaligned support for unknown architectures.

Fixes [2], [3]:

  ../gst/gstconfig.h:112:4: error: #error "Could not detect architecture; don't know whether it supports unaligned access! Please file a bug."
  #  error "Could not detect architecture; don't know whether it supports unaligned access! Please file a bug."

Subject: [PATCH] Fix unaligned access support for unknown architectures.
Better be safe (assume no unaligned access) than sorry (bail out
with error message at compile time).
Fixes compile for xtensa and microblaze architectures.
