fwiw, I've been using Mike Frysinger's crossdev utility on gentoo for
many years.  While it's tied closely to portage (can't live without it),
it has the advantage of automatic toolchain updates during regular
system updates.  Currently, I have the following on my build system:

  aarch64-unknown-linux-gnu-

  arm-none-linux-gnueabi-
  arm-none-linux-uclibceabi-

  powerpc-none-linux-gnueabi-

  mips-none-linux-gnueabi-
  mips-pc-linux-gnu-

  s390-none-linux-gnueabi-

  i586-pc-linux-gnu-
  x86_64-pc-linux-gnu-

Admittedly, I use the arm- one the most.

A while ago I looked at adding crossdev to gentoo-prefix (install gentoo
inside another OS, like OS X, or debian) which would then make the
utility much more useful.  But I never found the time to make it a
reality. :(

thx,

Jason.
