emulators/qemu-user-static linker error on 13-CURRENT r358890

13-CURRENT aarch64 GENERIC builds failed this week due to the dependent
port emulators/qemu-user-static failing to build, which is used by the
targets that create the cloud provider images (EC2, GCE, etc.).

The error output from the port build is:

===>  Configuring for qemu-user-static-2.11.50.g20191211_3

ERROR: We need to link the QEMU user mode binaries at a
       specific text address. Unfortunately your linker
       doesn't support either the -Ttext-segment option or
       printing the default linker script with --verbose.
       If you don't want the user mode binaries, pass the
       --disable-user option to configure.

The machine was upgraded yesterday from r356986 to r358890, and there
does not seem to be any relevant change to the port.

Any ideas?
