/usr/bin/gpg-error-config should only be used for native building.  For
cross-building it is expected that a dedicated gpg-error-config script
is installed in the root directory of the host platform (e.g. as
/usr/i686-w64-mingw32/bin/gpg-error-config) and only that
gpg-error-config should ever be considered.  In past this required
manual configuration but meanwhile SYSROOT seems to be an accepted
standard and we can make use of it.  This means to only look there for
the config script to get the right version and not take whatever we find
and only print a warning if the platform is wrong.


Shalom-Salam,
