No problem, moved it here.

This is where it gets hairy. When i supply a path in --with-ssl, it
finds the pkgconfig paths, when i set PKG_CONFIG_PATH it doesn't find
ssl at all.

env PKG_CONFIG_PATH=${ARM_TOOLS_DIR}/usr/local/ssl/lib/pkgconfig
./configure --host=arm-none-linux --with-ssl

The path is correct, and it holds *.pc files with the correct paths to
the libraries, yet:

Yes, these are correct.

Yes. although only static library .a files, not .la, would this perhaps
give libtool problems?

I just noticed, it's not linking against the libraries! No wonder its
complaining about missing symbols. It seems like it's missing -lssl and
-lcrypto

If i try linking manually with these included then it works. Bug in the
build system?
