are there changes for building mlvm now that 1.7 is released?

When we get the bsd-port changes folded into hsx, these ugly patches will go away.

I removed the bsd-port forest in sources and ran:

  hg fclone http://hg.openjdk.java.net/hsx/hotspot-comp sources

Re-created the ALT_COMPILER_PATH dir and symlinks to gcc 4.0 compilers

Updated my build scripts (https://gist.github.com/243072) to use the latest steps in:

  patches/README.txt

but am getting these errors now:
