I regret, but I don't recall the details.

Normally, there are 2 reasons for us to remove a multilib:
- Support for a multilib-variant is missing in RTEMS
- Nobody uses a multilib-variant.

IIRC, both had applied in this case.

c.f. above.

The initial, minimum requirements for me to add the mips32/EL multilib 
would be to know "gcc/newlib and rtems compiles" and to know people are 
actually using it.

I have no idea, whether RTEMS even compiles for mips32/EL nor do I know 
if the results are usable. I can try to activate mips32/EL multilib in 
my next toolchain spin and watch for what will happen ;)
