Compiler-RT for ARM-EABI target

Hi,

Is there a way to (cross-)build the compiler-rt for an ARM-EABI target?

I read the comments in the associated Makefile, so I understand it
cannot be easily done when builing clang.

However, is there a way to build the compiler-rt for another plaftorm
but the host, once clang & llvm have been successfully built?

Thanks,
Manu.
