New Revision: 349928
URL: http://svnweb.freebsd.org/changeset/ports/349928
QAT: https://qat.redports.org/buildarchive/r349928/

Log:
  First bit of support to cross build the ports tree will only work
  with simple ports for now, lots of improvements are pending
  
  cd devel/pkgconf; make X_BUILD_FOR=armv6-freebsd10.0 package
  
  Will create a armv6 ready package
  Note that right now the generated package does not have the proper ABI defined
  But the content is the right one
