Sorry, there is no documentation that I know of, and they don't have a
formal spec. From the commit history the earliest -debug targets (for
linux-x86, solaris-sparc and win32-x86)) were created by Janet Anderson
in 2003. In 2005 she added the linux-x86_64-debug files, possibly
contributed by Ernest Williams, and various other targets have also been
added and minor changes made over the years, although Janet was almost
always the person working on them. She retired last year.

The main differences from the non-debug version are that compiler
optimizations are usually turned off and debug symbols turned on
(although for workstation-OS targets like Linux those symbols are
usually turned on in the non-debug versions anyway since they don't take
up any memory space at runtime).

We have never actually promised that the -debug targets are configured
appropriately; if you want to use them the CONFIG files are usually
there but their configuration may be incomplete — fixes welcome!
