adding ecw variant to gdal @3.9.1_1+jpegxl+lto+mysql57+native+netcdf+opencl+openexr+openjpeg+postgresql16+proj9+xerces fails to build at ~95%

[TheLastLovemark]

installed ECWJP2SDKSetup_5.5.0.2268 to ~/ECW

then mv -f ECW /opt/local/lib.

followed by chown root:wheel /opt/local/lib/ECW

and chown 644 /opt/local/lib/ECW

It was working until the last 5 or so %

Any chance this is related to #70461???

log attached.

Looks like it's not linking with the objc runtime for some reason.

I have unfortunately not been able to test or update the ecw variant as the SDK (still?) have no support for ARM (which is the only machine I have at my disposal).
