@keith do you, by any chance, remember why we had this restriction for .executable?
!= .staticLibrary seems like the right thing to do here.

hrm im not sure, maybe I got it from this https://github.com/apple/swift-driver/blob/7a96ffdd68dda2049cc2da005493b872ea43e3bc/Sources/SwiftDriver/Jobs/GenericUnixToolchain%2BLinkerSupport.swift#L272, I think you're right though

besides previously there was a check for excluding the fuzzer sanitizer for executables, so you might want that back a557d59#diff-d44ec7a906797a39be2e42ecb334167ae217537ad09a726d1f905c4ba9130200L365
