There would be build errors if multiple builds use the same SSTATE_DIR,
and the builds use the different versions' docbook-sgml-dtd-native, the
problems are: we have multiple versions docbook-sgml-dtd-native:
docbook-sgml-dtd-3.1-native
docbook-sgml-dtd-4.1-native
docbook-sgml-dtd-4.5-native
And they depend on sgml-common-native which installs the file
sysroot/etc/sgml/sgml-docbook.cat, this file is also included in the
sstate cache file (.tar.gz), but both the 3 versions
docbook-sgml-dtd-native may update the
sysroot/ect/sgml/sgml-docbook.cat, and it is a hardlink to
SYSROOT_DESTDIR/etc/sgml/sgml-docbook.cat, so the sgml-docbook.cat in
the sstate cache file may contain the
docbook-sgml-dtd-<version>-native's info, and there would be errors when
we mirror the sstate-cache to another build which uses a different
version.
Now we exclude the sgml-docbook.cat from the ${D}, and generate
sysroot/ect/sgml/sgml-docbook.cat dynamically will fix the problem, both
the sgml-common-native and docbook-sgml-dtd-<version>-native can update
it it correctly.
The similar to docbook-dsssl-stylesheets-native and openjade-native.
