Subject: Fix 'make headers_check' on biarch architectures
From: David Woodhouse <dwmw2@xxxxxxxxxxxxx>
We generate an <asm/foo.h> which includes either <asm-$ARCH/foo.h> or
<asm-$ALTARCH/foo.h> as appropriate. But we were doing this dependent on
whether the file in question existed in the _unexported_ tree, not the
exported tree. So if a file was exported to userspace in one asm- directory
but not the other, the generated file in asm/ was incorrect.
This only changed the failure mode if it _was_ included from a nice #error to
a less explicable #include failure -- but it also gave false errors in 'make
headers_check' output. Fix it by looking in the right place instead.
