output of the make command

I tried to follow the instructions at <a href="http://clang.llvm.org/get_started.html">http://clang.llvm.org/get_started.html</a> to
build a debug version of clang ( I need this to troubleshoot persistent
problems with clang-3.3 and associated tools on Linux.)

anyway, had to upgrade gcc to 4.8 (I'm on ubuntu 12.04, which had gcc4.6). 

ran configure with:

../llvm/configure CC="/usr/bin/clang" CXX="/usr/bin/clang++"

compling seemed to go without issue, but it failed onthe link step with a
useless error message.

make TOOL_VERBOSE=1 log attached.

I'm now trying to configure with CC=gcc etc. to see if that works.</pre>
