Subject: [PATCH] Add a SONAME to the pppd binary

This hack inserts a SONAME into the pppd binary, which allows us to
run dpkg-gensymbols/dh_makeshlibs over the resulting binary. This is
useful so that we can use Debian's standard build infrastructure to
help track the ppp binary's ABI, which is used by plugins.
