Subject: [PATCH] Changed when to enable custom baud by default

Be very conservative when enabling custom baudrate
support (USE_CUSTOM_BAUD) by default. Only enable (by default) on
systems where we know it will cause no problems. For other systems the
user can try to enable it explicitly (see Makefile).

Currently enabled by default on:

  Linux, Kernel verison > 2.6.0, x86 and x86_64 architectures
  FreeBSD, OpenBSD, NetBSD, DragonFly BSD
