Improve the Debian mips, mipsel and mips64el ports

Description of the project: The Debian mips and mipsel ports have been around for a long time. The Debian mips64el port has been around for a short time. There are packages which could build and need some porting. Also, some of the recently uploaded packages stop building and we need to investigate what's causing the failures. The quality of Debian will be improved by fixing these problems. It is very common that a fix on one architecture is a similar fix on other architectures.
