Hello everyone,

Thanks to the previous patch for cross-libc, this patch is the only
change needed for cross-gcc to work properly when targeting GNU/Hurd.

Thank you,
Manolis

Subject too long; what about: “gnu: cross-gcc: Allow Hurd libraries to
be found.”?

Rather “Add ‘KERNEL/lib’ to ‘CROSS_LIBRARY_PATH’.”

Maybe write it as:

  (string-append libc "/lib:"
                 kernel "/lib")  ;for Hurd’s libihash

OK with these changes.

What’s confusing is that the hurd-core-headers package actually contains
libihash.a (and libstore.a?) in addition to headers, right?

Thanks!

Ludo’.
