Issue Description:

The following system module wrapper;

import PackageDescription

let package = Package(
    name: "CNCurses",
    pkgConfig: "ncurses",
    providers: [
        .Brew("ncurses")
    ]
)

When trying to build gives this error message:

swift build
error: nonWhitelistedFlags("Non whitelisted flags found: [\"-D_DARWIN_C_SOURCE\"] in pc file ncurses")

The pkg-config file that's being used:

# pkg-config file generated by gen-pkgconfig
# vile:makemode

prefix=/usr/local/Cellar/ncurses/6.0_2
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/ncursesw
abi_version=6
major_version=6
version=6.0.20150808

Name: ncursesw
Description: ncurses 6.0 library
Version: ${version}
URL: http://invisible-island.net/ncurses
Requires.private:
Libs:  -L${libdir} -lncursesw
Libs.private:
Cflags:  -D_DARWIN_C_SOURCE -I/usr/local/Cellar/ncurses/6.0_2/include -I${includedir}

What's the error here; is this pkg config file not supported at all? Does it require alterations? Is SwiftPM lacking in this regard? As a user, it's a very confusing error message. What's the fix-it?
