Thanks for adding the feature to ld! However, I think a
symbol-oriented option likely works better than a section-oriented
option.

https://maskray.me/blog/2020-11-15-explain-gnu-linker-options#symbol-ordering-filefile

This option (--symbol-ordering-file=) is unique to ld.lld. gold has a
--section-ordering-file, sorted by section name. In practice, text and
data sections mostly have different names. However, clang
-fno-unique-section-names (GCC feature request
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95095) can create
sections of the same that defeat --section-ordering-file.
