Re: git: cdcd52d41e24 - main - irdma: Add RDMA driver for Intel(R) Ethernet Controller E810

Yeah, I was able to repro it and get what I think is the error in a
nicer-to-read set of lines:

Building
/root/build/head/obj/root/build/head/src/amd64.amd64/lib/ofed/libirdma/libirdma.a

building static irdma library

Building
/root/build/head/obj/root/build/head/src/amd64.amd64/lib/ofed/libirdma/libirdma.so.1.full
building shared library libirdma.so.1

/usr/local/bin/x86_64-unknown-freebsd14.0-ld: duplicate expression `*' in
version information
collect2: error: ld returned 1 exit status

*** [libirdma.so.1.full] Error code 1


What does that even mean? I don't know anything about building libraries.
