you could try

Denx ELDK 5.5 for MIPS
http://www.denx.de/wiki/ELDK-5/WebHome

or

Mentor Sourcery CodeBench Lite Edition for MIPS ELF
https://sourcery.mentor.com/GNUToolchain/subscription3537?lite=MIPS

Similar to ARM you can use the built-in libgcc implementation of U-Boot
with "export USE_PRIVATE_LIBGCC=yes" (before Kbuild/Kconfig) or
"CONFIG_USE_PRIVATE_LIBGCC=y".

Actually you would need a full multilib toolchain with different libgcc
or multiple toolchains to build all BE/LE and hard-float/soft-float
variants. But that is not feasible, so you should always set
USE_PRIVATE_LIBGCC. USE_PRIVATE_LIBGCC is also required for ELDK toolchains.

BTW: "MAKEALL -a mips" with the kernel.org toolchain and
USE_PRIVATE_LIBGCC works
