Add an autoconf option for turning on -gsplit-dwarf by default
when building llvm. This saves quite a bit of time and space when linking. Please report any problems via bugzilla. Caveats: a) This will only work on linux b) This requires a fairly new binutils c) This requires a fairly new gdb git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184808 91177308-0d34-0410-b5e6-96231b3b80d8
