+Build system
+The location of the gcc source and objects should be passed as options to a
+configure script rather than being hardwired into the Makefile.
+Determination of the target triple should be moved from the Makefile to a
+configure script.
+The plugin revision is created from the subversion revision.  What if people
+are using git etc?  Maybe it should be calculated in a configure script, but
+since that might not get run often perhaps the Makefile is the best place.
+Target subdirectories should have their own Makefiles, instead of assuming
+that there's only one source file and that it's called llvm-target.cpp.
+Currently the target directory (eg: i386) is calculated from the target triple
+(eg: x86_64-unknown-linux-gnu) using gcc's config.gcc script.  This should be
+done from a configure script, rather from the Makefile using the get_arch_dir
+The Makefile needs to know the LLVM target name (eg: x86) in order to pass it
+to llvm-config so as to get the libraries to link with for target codegen.
+This should be calculated in a configure script (presumably by a small program
+that uses the LLVM triple facilities to calculate it).  If we know this, then
+we might as well rename target directories like i386/ to x86/ instead, and
+eliminate use of gcc's config.gcc script.  This also means that LLVM_TARGET_NAME
+could be defined from the Makefile rather than being specified in llvm-target.h.
