The "GCC4.3.2, latest uclibc" part scares me.

You mean you are NOT using the ELDK provided target environment, which
- among other things - contains the libraries that were used to
  configure and build GDB abd gdbserver for the target?

Please try:

1) using a *clean* ELDK root file system environment, i. e. ONLY the
   tools and libraries that come with the ELDK.

2) use a glibc based invironment instead of uclibc (which  is  always
   good  for  some  nasty surprises, without compensating this by any
   significant benefits).
