So, I went ahead and cleaned makefile a little bit, squashing a couple of bugs
on the way, added Apache license boilerplates and uploaded the patch to
HARMONY-4640 '[drlvm][build] Makefiles for building native components of DRLVM'

The build works as a overlay on top of existing build system, as it currently uses
apr an other 3rd party libraries build by the ant build system. It deploys the
resulting binaries to the same deploy directories, in order to support quick
recompilation cycle if only native files were changed. This dramatically increases
effectiveness of development work if frequent recompilation are needed, especially
in the case of moved source files, which requires 'clean' step with the current
build system (~6-7 minutes on my machine), but makefiles allow for an incremental
recompilation (typicaly ~10-20 seconds).

I've tried makefiles only on Linux/x86, since that is what I have.

The functionality for the cross-platform configuration is designed in the makefiles,
however, the configuration itself is missing, and I need help from volunteers to bring
this build system to a fully configured state.

To make the experimentation and contribution to the build system development easier,
I've set up a git mirror of DRLVM repository on repo.or.cz. Use following commands to check out the copy

     $ git clone git://repo.or.cz/drlvm.git
     $ cd drlvm
     $ git checkout -b mob origin/mob

The branch 'master' is a pure mirror of SVN, and branch 'mob' contains the patch with the makefiles.
In order to facilitate easy integration of many patches, anonymous write access without password
is enabled with mob account [1]. The following command can be used to push patches to the repository

    $ git push ssh://mob@repo.or.cz/srv/git/drlvm.git mob

The only writable branch is 'mob'. Using this anonymously writable branch, anyone (including non-committers)
can contribute patches, and all modifications will be collected in one place without having to mail or
upload multitude of patches. It would be easier for me to review patches in this way as well.

So, if you are interested in having a more efficient and convenient build system for DRLVM, 
please help in porting it to more platforms.
