I faced the same issue recently and had to import the eclipse project 
from the existing makefile again.

One thing you could do:
- export the toolchain to a system absolute path, e.g. /opt/toolchains, 
by modifying BR2_HOST_DIR for example;
- register the toolchain with eclipse again (check what you have in 
~/.buildroot-eclipse.toolchains);
- import your project in eclipse again (from existing makefile I suppose?)
