Hi,

so after our mrustc upgrade to 0.9, we get the following when building rust 1.19.0
on guix master 4de63cf3fc0a831d75cb507456821104f24800c2 and i686-linux:

[...]

"libcore"
command "output/rustc-build/rustc" "-C" "linker=/gnu/store/y7dd2178bbpy7pl09fdn1r9412rc2mm3-gcc-7.4.0/bin/gcc" "-Z" "force-unstable-if-unmarked" "-L" "output/target-libs" "src/libcore/lib.rs" "-o" "output/target-libs/libcore.rlib" failed with signal 8

That's extremely good, but signal 8 is SIGFPE, as before.
