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.
