The EXTRA_STRIPFLAGS variable can be used to pass additional parameters to the
strip command.
This can be used to remove additional sections or to keep symbols.
The removal of additional sections can be useful to enable reproducible builds.
Sections which contain paths or md5sums of the debug binaries (like
gnu_debuglink)
can be eliminated with this flag.
