	Replace it with llvm-config.h, which defines a subset of config.h's macros "so that they can be in exported headers and won't override package specific directives", e.g., PACKAGE_NAME. Endian.h wasn't using any macros at all though, so just delete the include there instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133712 91177308-0d34-0410-b5e6-96231b3b80d8
