[ELDK] Kernel selection determined by toolchain?

OK.

Out or curiousity: what exactly is your reason for using uClibc?

This is, at least in this wording, mostly a misconception.

Fact is that the header files you are using when linking your
application code should be the very same header files that were used
to build the toolchain. Period.

But as long as the Linux kernel does not  change  it's  API  to  user
space  applications  (which  might  happen,  but  it's  a  pretty big
exception), the Linux kernel is completely independent from the  tool
chain, the system libraries and the aplication code.

Just look in the target's /lib directory and you will see
libuClibc-0.9.27.so - so ELDK 4.1 includes uClibc version 0.9.27.

Use any 2.6 kernel version you like; recent ones preferred :-)
