[swift-build-dev] Building Swift Package Manager on ARM

[Joseph Bell]

Howdy,

I'm looking to getting the Swift Package Manager building on ARM systems
such as the BeagleBoard, and its now in the bootstrap stage, and bombs out
which what appears to be a linking error.  I know that
_TMaC18PackageDescription7Package
is defined in libPackageDescription.so but its not being picked up when
Package.swift is compiled.

That issue aside, what is the meaning of the "driver-mode" option to
swiftc, and why would one invoke swiftc with --driver-mode=swift?
