[LLVMdev] Compiling llvm and Clang in solaris 10

[Norm Jacobs]

I ran into this earlier in the week on the current Solaris development 
builds and I think that one of my co-workers was going to file a bug on 
it.  Basically, Solaris doesn't have an endian.h, so you have to patch 
include/llvm/Support/Host.h to define BYTE_ORDER as it would on linux 
and some other platforms.
