Hello,

While building a childhurd for core-packages-team I noticed that gnumach is currently build with the i686-linux toolchain rather than the i586-pc-gnu cross toolchain with a comment that a cross-built mach has issues. As I wanted to avoid bootstrapping a second toolchain I tried a to cross-build one and found no issues.

I then tried this is also on master with both i586-pc-gnu and x86_64-pc-gnu and have not noticed something (yet?) that indicates that mach is broken, the system boots and I was able to talk to the guix-daemon.

I marked the target as a [hurd-team] branch in case there is need for some more testing.
