Okay, so creating a config.site in binutils.mk like this:

    # install site-wide autotools config files
    $(INSTALL) -d '$(PREFIX)/share'
    echo ac_cv_build=`'$(1)/config.sub' $$($(1)/config.guess)` >
'$(PREFIX)/share/config.site'
    $(INSTALL) -d '$(PREFIX)/$(TARGET)/share'
    cp '$(PREFIX)/share/config.site' '$(PREFIX)/$(TARGET)/share/config.site'

works for 14 of the 15 packages with outdated config.* files. The
exception is openexr.mk, which builds a native ilmbase with a
temporary prefix. In this case, it's probably simplest to just keep
the patch.

The above doesn't require config.sub to be installed, so we could
remove that step.

I can't test if this technique also solves the wine detection problem,
though I suspect it may, possibly with the addition of "build=" to the
config.site file. If it does, we wouldn't need to install config.guess
either.

Mark, do you feel like testing if the config.site variables bypass the
cross-compile detection and remove the need for "--build" in the
wine-affected packages? You don't need to restart the build from
scratch, just create the '$(PREFIX)/$(TARGET)/share/config.site' file
and ./configure will use it.

Thanks,

Tony
