[ELDK] problem with 4.2beta: libtool has hard coded paths

[Douglas, Jim (Jim)]

Following installation of eldk4.2beta into /opt/eldk, 
/opt/eldk/ppc_6xx/usr/bin/libtool contains a number of hard coded paths,
such as:

SED="/opt/eldk/build/ppc-2007-11-27/work/bin/sed"
LD="/opt/eldk/build/ppc-2007-11-27/work/usr/powerpc-linux/bin/ld"

These paths prevent ppc_6xx-rpmbuild from building a number of target
packages from their srpm.  

The fix seems to be SED=sed and LD=ld, because the PATH will find the
correct binaries anyway.
