The autogen-native built error on FC17:
ccache: failed to create /dev/null/.ccache
This is because the gcc of FC17 is a symlink to ccache, so the ccache
will always be used regardless to the user's setting, ccache uses
$HOME/.ccache as the CCACHE_DIR if it has not been set, and autogen set
HOME=/dev/null.
Assign CCACHE_DIR the default value to preven it uses $HOME/.ccache
would fix the error.

Could we just set CCACHE_DISABLE ?
I'm afraid not, it still has the same error if we just set CCACHE_DISABLE,
this is a bug of ccache 3.1.7, it may be fixed in ccache 3.2.
In fact could we just set that globally?
I'm afraid I don't like fixing this on a per recipe basis...
I think that this is only needed by the recipe which set HOME=/dev/null,
the autogen-native is the only one as far as I know, yes, fix it globally
would be better (disable it explicitly if it is not enabled), I will send a V2.
