Bug Description: build links wrong libdb on 64-bit systems
Reviewed by: ???
Files: see diff
Branch: HEAD
Fix Description: Once again, libtool attempts to be helpful but is 
instead harmful.  If you have both db4-devel.i386 and db4-devel.x86_64 
installed, this will install /usr/lib/libdb-4.N.la.  If you use libtool 
to link with -ldb-4.N, and you do not specify a search path, libtool 
will attempt to find this library in it's default search path, which is 
something like /usr/lib/gcc/x86_64/blahblahblah/../../../lib.  This will 
find /usr/lib/libdb-4.N.la and will use the information in that file and 
link the object with /usr/lib/libdb-4.N.so, instead of just passing 
-ldb-4.N through to the linker which is what it ought to do (darn 
libtool).  In order to make libtool do the right thing, we must pass in 
-L$libdir -ldb-4.N to libtool so that it will use $libdir first in its 
search path.
Platforms tested: RHEL5 x86_64, RHEL4 x86_64
Flag Day: yes - autotool file changes
Doc impact: no
