Similar to what I did in gdbarch.sh/gdbarch.c, this patch uses
host_address_to_string to transform addresses into strings, rather
than printing them as longs...

        * arch-utils.c (gdbarch_update_p): Use host_address_to_string
        to print the address of the gdbarch pointer.

Tested on x86-linux. Will commit at the same time as the gdbarch.sh
patch if there are no objections.
