I am working on the cross-base patch so we can merge it with wip-hurd as well, but some problems need to be discussed.
First, in glibc/hurd headers we need to redeclare #:configure-flags with less flags.
We shouldn't but because we use the same configure flags as in glibc and glibc/hurd, we get an error at (string-append "--localedir=" (assoc-ref %outputs "locales") "/share/locale") when it tries to find the locales output.
>In unknown file:
> ?: 0 [string-append "--localedir=" #f "/share/locale"]
I attached the log.
Second, in glibc/hurd headers again, because we Don't use the same phases as in glibc and glibc/hurd, and as a result we don't have the pre-configure phase of glibc, /bin/pwd is not substituted with pwd and we get a "no such file" error.

In order to solve this I just need to add a pre-configure phase with just
(lambda _
(substitute* "configure"
(("/bin/pwd") "pwd")))
attached log.
Third, in glibc/hurd the permissions in chmod "bits/pthreadtypes.h" should be 666 not 555.
With this changes glibc/hurd can be built using the i686-pc-gnu cross toolchain.
I attached the patch and I made sure that there will be no regressions with the cross-base patch.
I wrote a simple commit message because it needs to be merged with the current glibc/hurd patch in wip-hurd.
Thank you,
Manolis
