Issue Description:

Invoking swiftc with "-F /path/to/foo.framework" gets passed to the linker as the same thing. It should get passed to the linker as "-F/path/to" since ld wants it in that format.

This can be worked around by adding in both "-F /path/to/foo.framework" and "-Xlinker -F/path/to".

Example arguments:

-emit-library -target x86_64-apple-ios10.3 -sdk /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator10.3.sdk -I /var/folders/jq/jq6r64mn1wvg18lp0bw71f780000gn/T/8f4d687f-7ac5-4d67-af47-eb8dc499c574 -I /Users/steveh/Projects/swiftdemo/lib/iphone/FinalProduct/x86_64 -L /Users/steveh/Projects/swiftdemo/lib/iphone/FinalProduct -F /Users/steveh/Projects/SimpleLib/someoutput/Debug-universal/SimpleLib.framework -L /Users/steveh/Projects/swiftdemo/bin/swift/lib/swift/iphonesimulator/ -lXamGlue -framework SimpleLib -v -emit-module -module-name XamWrapping SimpleLib-IdentityThing.swift

Addendum:

swiftc accepts either `-F /path/to/foo.framework` or `-F /path/to -framework foo`.

ld accepts either `-F /path/to -framework foo` or `-F/path/to -framework foo`.

ld does not accept `-F /path/to/foo.framework`

shrug

My ld accepts both forms. What ld are you using?

Comment by Steve Hawley (JIRA)

The issue has to do with ld requiring a -framework foo and swiftc does not.

It's not a big deal, and I'd just as soon close the issue.
