Making all toolchains print final compiler message.

This functionality was already present in the ARM toolchain script, but
this commit adds this across all toolchain scripts. Solves an issue that
cropped up where a build error wasn't being printed unless the verbose
flag was used. This should now print any existing error messages that have
been printed when the compiler output is being parsed.
