Summary:                    cmTryCompileExec fails on AIX 5.2
Description: 
bootstrap; gmake works (given compile issues as per Issue 13148).

Atempting to build the Example fails with a link command error in
cmTryCompileExec. This is true whether gcc or xlc is used.


Steps to Reproduce: 
Build cmake on AIX 5.2. Then:

$ cd Example
$ ../bin/cmake -G "Unix Makefiles"
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- broken
CMake Error at
/home/jim/work/src/cmake-2.8.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):
  The C compiler "/usr/bin/gcc" is not able to compile a simple test program.

  It fails with the following output:

Additional Information: 
This failure happens on 2.8.7 and 2.8.8. 2.6.4 works fine.

link.txt for the failing gcc on 5.8.8 is:

-o cmTryCompileExec732778660  /usr/lib /lib

On 5.6.4 for the successful g++ is:

/usr/bin/g++          CMakeFiles/cmTryCompileExec.dir/CMakeCXXCompilerABI.cpp.o 
-o cmTryCompileExec -Wl,-brtl,-bnoipath,-bexpall -Wl,-blibpath:/usr/lib:/lib
