Problem Description
One project I'm working on isn't building since I updated Xcode.
Note that I am building the exécutable with swift build (not Xcode).
Details
The command that is failing is :
swift build -Xswiftc -static-stdlib -Xswiftc -DDEBUG
I am trying to make a static build. When just try swift build, it works.
The error
I'm copying the beginning of the error output only (the rest is too long):

Note that I've renamed the project and library names for anonymity.

Swift version after update
Running
swift -version
in the command line returns :
