Extended Description

Bad:

ddunbar@frank:CodeGen$ echo "#include <stdarg.h>" | clang -isysroot /over/the/rainbow -v
ignoring nonexistent directory "/home/ddunbar/llvm.trunk/Debug/Headers"
ignoring nonexistent directory "/usr/local/include"
ignoring nonexistent directory "/usr/include"
ignoring nonexistent directory "/System/Library/Frameworks"
ignoring nonexistent directory "/Library/Frameworks"
#include "..." search starts here:
End of search list.
:1:10: fatal error: 'stdarg.h' file not found
#include <stdarg.h>
^
clang version 1.0 based upon llvm 2.6svn hosted on i686-pc-linux-gnu
1 diagnostic generated.

Also, the ignoring ... warning should probably print using the mapped path to avoid serious confusion.
