GDBM upgrade in F17

[Petr Pisar]

Jan Horak (hhorak) is going to upgrade GDBM to version with new SONAME
in F17. Because rel-engs refused to provide dedicated build root, the
upgrade will be performed in F17 directly.

That means Perl, Pyhon and other default-build-root packages will
disable support for GDBM temporarily. So if your package needs GDBM
support in those languages, please wait until new GDMB and other
packages (Perl, Python and similar) get recompiled again against this
new GDBM.
