Remove most references to LLVM_LIB_SEARCH_PATH. It now only exists in the

GettingStarted.html document in the environment section and only as an
optional feature.

<div class="question">
<p>
When I use the test suite, all of the C Backend tests fail. What is
wrong?
</p>
</div>
<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/&lt;<i>platform</i>&gt;/llvm-gcc/lib</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/lib</tt> subdirectory.

<div class="answer">
<p>
In order to find libcrtend.a, you must have the directory in which it lives in
your LLVM_LIB_SEARCH_PATH environment variable. For the binary distribution of
the LLVM GCC front end, this will be the full path of the <tt>lib</tt>
directory inside of the LLVM GCC distribution.
</p>
The only way this can happen is if you haven't installed the runtime library. To
correct this, do:</p>
<pre>
% cd llvm/runtime
% make clean ; make install-bytecode
