Unfortunately MIPS Technologies doesn't maintain an ABI document
beyond the old psABI from e.g.
ftp://ftp.linux-mips.org/pub/linux/mips/doc/ABI/mipsabi.pdf.
Practically this means that the GNU Toolchain is the ABI reference
implementation. The changes are mentioned in the GCC 4.3.0 release
notes at http://gcc.gnu.org/gcc-4.3/changes.html:
"GNU/Linux configurations now generate -mno-shared code unless
overridden by -fpic, -fPIC, -fpie or -fPIE."

As things stand, you will have to ask for that any of:
- CodeSourcery, who maintains the Toolchain for MIPS. (That's
probably Maciej W. Rozycki now.)
- the GCC MIPS maintainers, that's Richard Sandiford and
Eric Christoper.
- the binutils MIPS maintainers, that's also Eric, and myself.
- The guy who proposed the change originally, AFAIR that was
Ian Lance Taylor (on the binutils list.)
