Cannot link correct libltdl.so. Is it a bug?

[Gary Yang]

I got errors when I do the cross compile for powerpc. Below are the error 
messages. It looks for /usr/lib/libltdl.so instead of 
/tools/eldk/4.2/ppc_4xx/usr/lib/libltdl.so at link time. I set the path 
-L/tools/eldk/4.2/ppc_4xx/usr/lib. But, it is useless. Below are details.

Before running ./configure, I set the environment variables below

setenv LDFLAGS  -L/tools/eldk/4.2/ppc_4xx/usr/lib
setenv CPPFLAGS -I/tools/eldk/4.2/ppc_4xx/usr/include

setenv CROSS_COMPILE ppc_4xx-
setenv ARCH powerpc
setenv BUILD_CC gcc
setenv CC powerpc-linux-gcc
setenv AR powerpc-linux-ar
setenv RANLIB powerpc-linux-ranlib
set path=(/tools/eldk/4.2/bin /tools/eldk/4.2/usr/bin $path)

./configure --prefix=/tmp/safebox/install_libs --host=powerpc-linux 
--build=i686-pc-linux-gnu -target=powerpc-linux

./configure runs successfully with the following warnings

Can someone tell me how to run configure so that it looks for 
/tools/eldk/4.2/ppc_4xx/usr/lib/libltdl.so instead of /usr/lib/libltdl.so?
Is it a bug?

Thank you
