It is not clear why you are trying to add this as compile-time 
option.  The Expect header is defined by the HTTP standard, and 
compiling nginx without appropriate support looks clearly wrong.

If Google Cloud fails to properly balance HTTP and needs special 
workarounds on nginx side, you may consider adding this as a 
run-time option instead, similar to the 
"chunked_transfer_encoding" directive, see 
http://nginx.org/r/chunked_transfer_encoding.

Or, better yet, report the bug to Google.  It should be more or 
less trivial for them to fix this by just removing the Expect 
header from forwarded requests.
