bootstrap change to not require wget, for the buildbot

[Paul Eggert]

I observed the test failure due to the recent dircolors fix on
Solaris 10, so it's not just an HP-UX thing.  Jim is the expert in
that area, though.

I also noticed that the buildbot was failing on ia64 hpux11.23 hpcc
32-bit and 64-bit due to a failed configure, because these platforms
lacked 'wget'.  'wget' is needed only for translations, and I think
it's better to keep going and build with zero translations if 'wget'
isn't working, so I installed the following patch to 'bootstrap':

2006-08-26  Paul Eggert  <address@hidden>

        * bootstrap (get_translations): Skip this if WGET_COMMAND is empty.
        Fail if the first "echo" fails.  Suppress diagnostics from "ls po/*.po"
        since there might not be any .po files.
        (WGET_COMMAND): Set to empty if wget doesn't
        seem to be available.  Don't export; shouldn't be needed.
