llvm r110109 defines LLVM_NATIVE_ARCHNAME
http://llvm.org/viewvc/llvm-project?view=rev&revision=110109

If X86 are defined then when calling
InitializeNativeTargetAsmPrinter()

the macro expands into
LLVMInitializeAsmPrinter() that dont exist.
instead of
LLVMInitializeX86AsmPrinter() that do exist.

In function 'bool llvm::InitializeNativeTargetAsmPrinter()':
/home/xerxes/llvm-configure-shared/../llvm/include/llvm/Target/TargetSelect.h:125:
error: 'LLVMInitializeAsmPrinter' was not declared in this scope


I have attached a proposed patch that fixes this behaviour by resolving what
LLVMInitialize${NATIVE_ARCH}ASMPrinter and
LLVMInitialize${NATIVE_ARCH}TargetInfo to use at config.h generation time.

I need help regenerate configure and commiting this by someone who have a
working autoconf 2.60 setup.
