- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

Note that I seriously doubt that this perticular construct is useful,
though: it's a pointer in an alternate address space pointing into
unqualified address space.
