 This patch includes changes to allow programs and packages to be disabled
 by stage when building GHC.

 == rule/build-package.mk ==
   * Add guards for "disable-$(dir)-$(stage)" around the rule body

 == rule/build-prog.mk ==
   * Add guards for "disabled-$(dir)-$(stage)" around the rule body

 == mk/build.mk.default ==
   * Add a set of package disabling definitions when $(Stage1Only) is set
 to "YES"

 == rts/ghc.mk ==
   * Add the all_rts target as a dependency for all, causing the rts to
 build when packages that depend on it are disabled
