Better build support for custom baudrates

Browse Source 
For some systems (OSes, versions, architectures) custom-baudrate
support is enabled by default.

For others, support may work, but must be enabled by defining
USE_CUSTOM_BAUD in the Makefile

You can also disable custom baudrate support altogether (even for
systems where it's enabled by default), by defining NO_CUSTOM_BAUD in
the Makefile
