Cross compiling pppd 2.4.1 with ELDK 2.0

I am currently trying to crosscompile pppd with the ELDK 2.0 toolchain.
To build in a native Intel RedHat 7.2 environment was no problem.
However, when trying to crosscompile it seems that there are more things than CC and the PATH to be altered. By changing the include file search path, I was able to build chat, but pppd seems to be a little harder. Is there anyone out there that might have some clues?

Kind regards,
