`raco exe' doesn't use the system linker (in the sense of `ld') at all. It clones an existing binary and then adds an extra load command by manipulating the Mach-O format directly. Flags added by `++exf', meanwhile, are flags to the embedded `racket' or `gracket' in the executable.
I'm not sure how you'd add a section to an already-linked executable. Maybe `libtool' can do that. It's possible that you could adapt the code in "collects/compiler/private/mach-o.rkt" to add a section, but I'm not sure how difficult it is to add a section as opposed to a load command. It may be easiest to change the linker command in the Makefile when building racket or gracket to add the `-sectcreate' flag. Then, when `raco exe' clones the binary, your extra section would be there.
