Debian GNU/Linux supports both little and big endian machines. Information about it can be found in the Debian Wiki and at the MIPS Port page. The old-stable version "sarge" uses only 32 bit 2.4 kernels. The stable version "etch" supports 64 bit 2.6 kernels on most machines.
T2 is an open source (GPL) System Development Environment supporting many different architectures including MIPS with both, little and big endian. Information about the T2 MIPS support can be found at MIPS and MIPS64 pages as well as on the general T2 homepage. The Open T2 SDE is suited to create specialized embedded Linux targets as well as run on Sgi workstations.

A set of distributions is maintained by Maciej at ftp://ftp3.ds.pg.gda.pl/people/macro/. Included, in the order of decreasing completeness, there is a 32-bit little-endian, 64-bit little-endian, 32-bit big-endian and 64-bit big endian one. The 64-bit ones only support the (n)64 ABI.
The former mirror at ftp.rfc822.org is now gone. Thanks, Florian, for providing this service over the years.
Gentoo Linux is a source based distribution which suports many different architectures, including MIPS. Currently two platforms are supported; Silicon Graphics Workstations, and Cobalt servers.
