gstreamer1: fix compile for microblaze and xtensa architectures

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.
