Added a remark about setting LLVM_LIB_SEARCH_PATH.  I forgot to do this on
PowerPC, and it made the test results scary.

+<div class="answer">
+<p>
+If you build LLVM and the C Backend tests fail in <tt>llvm/test/Programs</tt>,
+then chances are good that the directory pointed to by the LLVM_LIB_SEARCH_PATH
+environment variable does not contain the libcrtend.a library.
+</p>
+
+<p>
+To fix it, verify that LLVM_LIB_SEARCH_PATH points to the correct directory
+and that libcrtend.a is inside.  For pre-built LLVM GCC front ends, this
+should be the absolute path to
+<tt>cfrontend/<<i>platform</i>>/llvm-gcc/bytecode-libs</tt>.  If you've
+built your own LLVM GCC front end, then ensure that you've built and installed
+the libraries in <tt>llvm/runtime</tt> and have LLVM_LIB_SEARCH_PATH pointing
+to the <tt>LLVMGCCDIR/bytecode-libs</tt> subdirectory.
