libtool relinks against system libraries during make DESTDIR=... install

[Peter Volkov]

Hi. I'm looking for suggestion how to fix following issue:

I'm building wireshark-1.6.0 package which contains (among others)
following libraries:

wsutil/libwsutil.la (dlname='libwsutil.so.1')
wiretap/libwiretap.la

wiretap/Makefile.am has following lines to link with libwsutil.la:

libwiretap_la_LIBADD = libwiretap_generated.la 
${top_builddir}/wsutil/libwsutil.la $(GLIB_LIBS)
libwiretap_la_DEPENDENCIES = libwiretap_generated.la 
${top_builddir}/wsutil/libwsutil.la wtap.sym

At the same time my system has wireshark-1.4.7 installed and it also
have both libs, but with different versions - for this question it's
important that I have libwsutil.so.0 installed in my system. Now if try
to do staged install for libwiretap like this:

$ cd wsutil/ && make DESTDIR=/tmp/test install
$ cd ../wiretap && make DESTDIR=/tmp/test install

libtool relinks libwiretap.so against _system_ libwsutil.so:

Why libtool prepends -L/usr/lib -L/usr/local/lib before
-L/tmp/test/usr/lib64? How to force libtool link agains library inside
DESTDIR (library bundled with package) instead of system one?

libtool --config is in attachment.

Thank you in advance for any hints,

Peter.
