https://sourceware.org/pipermail/binutils/2021-December/118844.html

hopefully with some prompt response.
As that list seems to be mainly patches, should this be reported at:

https://sourceware.org/bugzilla/buglist.cgi?component=binutils&product=binutils

Thanks for tracing this issue back to its roots in March:

https://sourceware.org/git/?p=binutils-gdb.git;h=ba6eb62ff0ea9843a018cfd7cd06777bd66ae0a0

+  .debug_loclists ${RELOCATING+BLOCK(__section_alignment__)} 
${RELOCATING+(NOLOAD)} :
+  {
+    *(.debug_loclists)
+  }

resulting from:

https://sourceware.org/bugzilla/show_bug.cgi?id=27268

this section is required for Mingw but should not be in Cygwin,
although it was added to all of the below:
