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, DragonFly BSD
