With a bit tuning, Buildroot can work with a toolchain that does not
support shared libraries (so you can postpone the work on the dynamic
linker later on). But it needs to be a real toolchain, not a bare-metal
compiler on one side and the C library on the other side.

So before diving into the dynamic linking stuff and shared libraries, I
would recommend you to work on getting a proper toolchain built, either
with Buildroot or Crosstool-NG (I would suggest the latter). If you
have a working binutils/gcc/uClibc port, integrating the support for
your arch in Crosstool-NG should not be very complicated.
