[PATCH 2/2] xfsprogs: Fix --disable-static option build

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

Internal xfsprogs libraries are linked statically to binaries as
they are not shipped libraries. Using --disable-static prevents the
internal static libraries from being built and this breaks dead code
elimination and results in linker failures from link dependencies
introduced by dead code.

We can't remove the --disable-static option that causes this as it
is part of the libtool/autoconf generated infrastructure. We can,
however, reliably detect whether static library building has been
disabled after the libtool infrastructure has been configured.
Therefore, add a check to determine the static build status and
abort the configure script with an error if we have been configured
not to build static libraries.

This build command now succeeds:

$ make realclean; make configure; ./configure --disable-static ; make
