I fixed a lot of ports in the run-up to merging llvm-17 in 15-CURRENT,
but I could not get them all.
The preferred way is fixing the port by removing the undefined symbols
from the linker version script in the port, but if that is not possible
or difficult, add -Wl,--undefined-version to the linker flags suppresses
the error. E.g. in the port Makefile:
LDFLAGS+=3D -Wl,--undefined-version
For an example, see:
