xfsprogs: .lai files not found

[Jan Engelhardt]

So I tried changing the xfsprogs package in openSUSE to build without 
static libraries, and what I got back from the build system was a 
warning about completely improper rpath settings.


	ERROR: RPATH "/home/abuild/rpmbuild/BUILD/xfsprogs-3.1.6/libxfs/.libs" 
	on 
	/home/abuild/rpmbuild/BUILDROOT/xfsprogs-3.1.6-0.x86_64/usr/sbin/mkfs.xfs 
	is not allowed
	[lots of these]

I therefore ripped out

	-LTLDFLAGS += -rpath $(PKG_ROOT_LIB_DIR)

from include/buildmacros, only to find that the install procedure then 
does not work at all anymore.

	cd ../libhandle/.libs; ../../install-sh -o abuild -g abuild -m 755 -d /lib64; ../../install-sh -o abuild -g abuild -m 644 -T so_dot_version libhandle.lai /lib64; ../../install-sh -o abuild -g abuild -T so_dot_current libhandle.lai /lib64
	install-sh: Unable to find libtool library file libhandle.lai
	install-sh: Unable to find libtool library file libhandle.lai
	gmake[1]: *** [install] Error 2
	make: *** [libhandle-install] Error 2
	error: Bad exit status from /var/tmp/rpm-tmp.JjlSJb (%install)

(I frown upon using libtool directly and seek to replace it with an
assisted version using automake. There is however __quite__ some
cruft in the src tree.)
