I broke the console output in July when I got the BSP to build for the head with "libbsd" but only recently got back to actually using this work, then I was focused on getting everything building for that target.  See the email "build of libbsd for powerpc fails with error:redefinition of 'eieio'".  Back then I moved definitions out of <bsp.h> and into <libcpu/io.h>, but I failed to put <libcpu/io.h> in the shared console, thinking code would fail to compile if they referenced the definitions.

That PowerPC shared console has the following "iffy" code with BSP_UART_IOBASE_COM1 no longer defined.  In console initialization it skips over that port when it sees the ISR entry point set to 0.

I'll have to revisit everything affected by that change to look for similar "#ifdef" logic.

    { "/dev/ttyS0",
#ifdef BSP_UART_IOBASE_COM1 <<< *No longer defined*.
