No,  the tree doesn't get a lot of uClibc use on the m68k processors,
the "LIBC:PRINTF" error you see is because uC-libc doesn't have floating
point compiled in.  If you want to use floating point,  link in -lm
something like:

	m68k-elf-gcc -m68000 -Wl,-elf2flt -o c c.c -lm -lc

The uCsimm target doesn't honour the CONSOLE_BAUD_RATE option in
config.arch,  you will need to hack the serial driver or the config/setup
code for the uCsimm to change this.

Someone here may know a better way or be able to tell you exactly how to do
