Possible Bug in directory search for link libraries on x86_64 linux

[John DeFranco]

On x86_64 systems it would seem that the search path for link libraries 
should be : /lib64, /usr/lib64, /lib, /usr/lib, etc. If not you end up 
getting the 32 bit libraries included first and then a link error. For 
example (cut down to only include the pertinent segments):
cc   -g -o test  o cl_rba_uds_test.o /usr/lib/libm.so \
       /usr/lib/libdl.so   objs/linux/md80.cup.hp.com/debug/cl_chain.o \
        -Lobjs/linux/debug -lmylib
/usr/lib/libm.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

In this case -lm and -ldl where sepecified as dependencies in the 
makefile. The proper path for /usr/lib/libm.so and /usr/lib/libdl.so 
should have been /usr/lib64/libm.so and /usr/lib64/libdl.so.

According to the doc I should be able to set this by a couple of methods 
(VPATH seems to be one), but I would think this should work right 
without me having to do that.
