I think so. I've just tried on x86_64-linux, with a statically
linked binary (I used gdb.threads/staticthreads, set a watchpoint
on semaphore), and although there are no shared libraries loaded,
the problem is masked by adding the symbols of the vsyscall page
(sysfile-mem.c:add_vsyscall_page). If I hack that function to
do nothing, I see that same thing you're seeing on djgpp.

Maybe there's a place for a generic fix? Somewhere after
having opened a connection to the target interface. I was
thinking of post_create_inferior, but sounds like opening
a connection to a remote target with "target remote" that
happens to not pull in any more symbols (like most embedded
targets) is having the same problem? Maybe there should be
a target_post_open ...
