Log Message:
Use "-O2 -fno-reorder-blocks" instead of "-Os" for m68k default optimization.

"-Os" was specfied when gcc 4.5.x was imported and the commit log says
"-O2 produces much bigger code with gcc 4.5 than it did with gcc 4.1"
but "-Os" disables most inline declarations and makes some applications
much slower.  "-O2 -fno-reorder-blocks" seems enough to reduce sizes
and disabling -freorder-blocks wouldn't cause particular performance
impact on ancient m68k machines with small cache memories.
See my post on port-m68k@ for more details:

No objection in the thread and "seems fine to me" from mrg@.
