building JDK for new platform

[Gary Benson]

Hi Robert,

I use IcedTea's bootstrap VM and plug replacements.  Build them with:

  hg clone http://icedtea.classpath.org/hg/icedtea
  cd icedtea
  ./configure
  make boot plugs

Then build the JDK with:

  export ALT_BOOTDIR=/path/to/icedtea/bootstrap/jdk1.6.0
  export ALT_CLOSED_JDK_IMPORT_PATH=/path/to/icedtea/bootstrap/jdk1.7.0

Cheers,
Gary
