In configure.ac CAIRO_ENABLE_SURFACE_BACKEND...

>quartz_LIBS="-Xlinker -framework -Xlinker CoreGraphics"

and

>quartz_LIBS="-Xlinker -framework -Xlinker ApplicationServices"

The -framework flag takes CoreGraphics or ApplicationServices as its own second argument, but the syntax here suggests that -framework and CG or AS are two independent linker flags...easy for a brain-dead build-tool to accidentally not keep them in order, or to purge the "duplicate" -framework one unless it knows that this is really a tied pair. A alternative that keeps -framework and its argument bound together, both for reading and for non-breakage by parsers, is -Wl,, which is specifically documented in the clang/gcc manpages as a way to pass flags that take arguments:

>quartz_LIBS="-Wl,-framework,CoreGraphics"
>quartz_LIBS="-Wl,-framework,ApplicationServices"
