Do you need to set all of those? Normally it's sufficient to run
configure with the right --host option. As far as I understand it
--target is only for things like compilers/assemblers that output
binaries. Not things like curl/libcurl. --build should be guessed
correctly.

So try unsetting all of these (except PATH) and then calling configure
with only --host, --prefix and --exec-prefix.

Are you sure "arm-linux-linux" is right? I would have thought just
"arm-linux" based on the names of the binaries in your toolchain.

So try this (after making sure you have UNset CC, AS, NM, etc., etc.):

./configure --host=arm-linux --prefix=... --exec-prefix=...

I think this is a symptom of your "arm-linux-linux" and may be the
cause of your problem.

I'm not sure if this warning is relevant, but I think they would
prefer something like "arm-unknown-linux" or "arm-unknown-linux-gnu"
instead of "arm-linux". You might find that there are binaries called
"arm-unknown-linux-gcc" etc. while the "arm-linux-gcc" etc. are just
symlinks to them.

I'm not sure why configure finds your gcc, but not ar and strip.

I don't know what "Invalid operation" means in this context, but I
suspect this is as a result of the wrong binaries being used when
trying to compile this code.
