 There's rather tool poor support for this feature so far. It e.g. requires 
relatively recent gdb (and IIRC the support was buggy in some versions, I'm 
not sure how well it works now. Neither ccache nor icecream support the 
option (for ccache there's a 3rd party patch that has not been integrated, 
for icecream I have a patch but compilers do not allow specifying proper path 
refering to the .dwo file when building in a different path).
