coreutils 8.30 "bootstap"

[Gabor Z. Papp]

lo lo,

I would like to "bootstrap/cross compile" coreutils 8.30 using a local toolchain
from x86_64 to i686.

Compiling works fine, and the generated binaries are correct, but when
manuals comes to play, help2info tries to execute the compiled
binaries to get the man pages from --help output, but the compiled
binaries are not executable on the host target, since its not
multiarch.

Generating the main pages will fail, and build terminates.

How could I solve this problem and let coreutils compile in this
environment?

Thanks
