Hi -

I was able to build gdal 3.10 in a little under an hour with `fedpkg
mockbuild` on the F42 buildroot. It was spending hours on
single-threaded `ar` calls. Is there any possibility of parallelizing
that?

See also rhbz2389629. The problem in both cases is that both these
builds have .a files with tens of thousands (!) of small .o files,
which indeed are processed serially. Parallelizing them a little bit
may be possible, but /bin/sh makes that a pain. For now, as mjw
suggests, consider disabling the new functionality with:
%undefine _preserve_static_debuginfo
This is not sufficient. I also had to add:
%define _find_debuginfo_opts --no-ar-files
