define Package/fakeuname/description
 Fakeuname is a host tool for cross-compile cross-platform builds
 if configure or/and build scripts check uname output for target 
 build and use invalid build flags. This tool should not be used 
 in normal case if configure/build scripts allow to redefine 
 required values instead of using uname output
