travis: enable building of the tools

For native (non-cross compiles) we now only require bcc, ld86, as86 for
building rombios, we can build the toolstack sans rombios and using the
system SeaBIOS due to known build issues. At the same time capture the
output of the configure scripts to help with tracking down future build
issues. This does not enable building of the toolstack with clang for
now due to multiple failures.
