For GNU autoconf-ed packages (the ones with a configure script), you
should also tell the package that you're actually cross compiling by
specifying the target platform (arm-unknown-linux-gnu):
setenv CC arm-linux-gcc
./configure [funny options] arm-unknown-linux-gnu
With a properly crafted configure script, the binaries needed to generate
the source files will be compiled with the system's native compiler, while
the final binary will be compiled with the cross compiler.
If that still doesn't work (like with bash), you need a native platform to
get things compiled. Compaq CRL has some hosts online to do this:
skiffcluster1.handhelds.org
skiffcluster2.handhelds.org

Jim Stud also has a Debian box which you can use for cross compiles.

Use "arm-linux-gcc -pring-search-dirs" and the compiler will tell you
about its directories.
