The libsemanage Makefile currently installs libsemanage.so.1 into
SHLIBDIR, but links libsemanage.so to libsemanage.so.1 in LIBDIR. This
means things will only work if SHLIBDIR and LIBDIR are the same.
Fortunately, by default, they are the same because the default of
SHLIBDIR is set to PREFIX/lib (same as LIBDIR default) instead of the
standard DESTDIR/lib. Unfortunately, if a user overrides SHLIBDIR, by
doing something like the following:
make DESTDIR=~/tmp/ LIBDIR=~/tmp/usr/lib SHLIBDIR=~/tmp/lib install
then a broken symlink is created. Note that in some cases this may still
work even when SHLIBDIR and LIBDIR are not the same, e.g.:
make LIBDIR=/usr/lib64 SHLIBDIR=/lib64 install
But this only works because, in systems like Fedora, /lib is a symlink
to /usr/lib, so SHLIBDIR and LIBDIR are the same even though it doesn't
immediately look like it.
This patch changes the libsemanage Makefile to set the default value of
SHLIBDIR to the standard DESTDIR/lib to prevent confusion, and installs
libsemanage to LIBDIR and completely ignores SHLIBDIR.
