It seems that libtool decides to set rpath based on .la files we have in 
staging. Some of them (e.g. glib provided libs, and libnl) set either 
'dependency_libs' (glib) or 'libdir' (libnl) to paths under output/build or 
staging. wireshark also links its own libraries (e.g. wiretap, epan) using 
local source tree .la files. I'm not sure how to solve this in the general 
case. It probably requires fixing up all these .la files.
