The test invokes 'go build' with a CC containing the arguments
-framework CoreFoundation. Previously, the go command split CC on
whitespace, and inserted the arguments after the command line when
running CC directly. Those arguments weren't passed to cgo though,
so cgo ran CC without -framework CoreFoundation (or any of the other
flags).
In CL 334732, we pass CC through to cgo, and cgo splits arguments
using str.SplitQuotedFields. So -framework CoreFoundation actually
gets passed to the C compiler. It appears that -framework flags are
only meant to be used in linking operations, so when cgo invokes clang
with -E (run preprocessor only), clang emits an error that -framework
is unused.
This change fixes the test by moving -framework CoreFoundation out of
CC and into CGO_LDFLAGS.
