try again to fix libmisc sharing problem

Issue #297 reported seeing

*** Warning: Linking the shared library libsubid.la against the
*** static library ../libmisc/libmisc.a is not portable!

which commit b5fb1b38ee was supposed
to fix.  But a few commits later it's back.  So try to fix it
in the way the bug reporter suggested.  This broke builds some
other ways, namely a few missing library specifications, so add
those.
