Debian multiarch support

Another solution could be searching in directories found at
/etc/ld.so.conf.d/*.conf or adding a new parameter. Here is a patch
which adds a new --libdirs parameter, and also a new inst_libdir_file
function which will try to expand metacharacters on each lib
directory:

    inst_libdir_file "libdevmapper-event-lvm*.so"
