[CMake] Contents of link.txt differ between Solaris 8 and Linux

[Tom Kacvinsky]

Hi,

I am using cmake 2.8.11.2 on Solaris 8 and  Ubuntu 12.04.2 LTS, built from
source using the GCC tool chain.

I noted that the link.txt for one of our binaries on Solaris 8 are:

/home/FLEXlm/FLEXlm_10/sun4_u5/lm_new.o -lm -lc -lc -lstdc++ -lm -lc -lc

Note the duplication of lm_new.o and several system libraries (-lm and
-lc).  This causes problems with GNU binutils as there are multiply defined
symbols when the lm_new.o object file is duplicated.  What I noted is that
this duplication does not happen on Linux:

What do you need from me in terms of helping diagnose this issue?

Thanks,

Tom
