So if my intent is to use the uClibc library exclusively on a given 
platform, there is no need for multilib support in the toolchain, 
correct?

I just saw in the .config file for buildroot that some features are 
only tested with multilib enabled.  I guess I won't worry about it 
until I run into problems.

I am assuming that including multilib support is likely to increase 
the size of the executables.  So I'd rather not use it.
