Building the libcore crashes with Illegal instruction

[paly2]

Hello,
I am trying to compile the rust compiler on a Raspberry Pi 2 (host: arm-unknown-linux-gnueabihf).

LLVM has been compiled in about eight hours (I used only one job for make, because on the very limited Raspberry Pi RAM), but finally it succeeded. The rust compiler (rustc) looks correctly built in arm-unknown-linux-gnueabihf/stage0/bin.

However, make fails with the following error log:
