This was r180041 and r180046, which was reverted in r180066. Re-committing this should fix the dragonegg bootstrap, which I presume needs LD_LIBRARY_PATH to be propagated to the child. Tested on Linux, Windows, and Mac OS 10.6. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180099 91177308-0d34-0410-b5e6-96231b3b80d8
