FTR, we are going to remove the mips architecture in the next weeks [1],
so the problem will be limited to mipsel soon.

Reducing the number of threads won't help, as the issue there is not the
memory available on the buildds (they have 8GB RAM), but the virtual
memory address space which on 32-bit mips limits the allocated memory
per process to 2GB. Other 32-bit architectures usually have a 3GB limit
instead.
I wonder how much memory is required to build rustc, if we are just
above 2GB, or already close to 3GB. Depending on that we might need to
find a solution or add an exception for mipsel only or also for the
other 32-bit architectures (armel, armhf, i386).
