[PATCH 0/2] misc fixes from crosstool-ng

[Chris Packham]

Crosstool-ng has been carrying these two patches for sometime. I'm not sure if
anyone actually tried to submit them upstream so I'm doing so now.

I can't speak with any authority on the m68k patch it appears to be at least
consistent with commit cf9d06b14 ("2010-02-08  Josef Wolf  <jw@raven.inka.de>").

The config patch seems to be consistent with other similar files so might just
be a longstanding bug no-one has noticed.

Chris Packham (2):
  m68k: disallow unaligned access for m68010 and m68020
  config/mt-d30v: Append flags

[PATCH 1/2] m68k: disallow unaligned access for m68010 and m68020

[Chris Packham]

From: Remy Bohmer <linux@bohmer.net>

Disable at least  m68010 and m68020. These processors certainly do not
like unaligned accesses.

[PATCH 2/2] config/mt-d30v: Append flags

[Chris Packham]

Append to CFLAGS_FOR_TARGET/CXXFLAGS_FOR_TARGET rather than replacing
them.
