This actually worked:
$ cat relink.log
(SHA256) /bsd: OK
LD="ld" sh makegap.sh 0xcccccccc gapdummy.o
ld -T ld.script -X --warn-common -nopie --no-mmap-output-file -o newbsd
${SYSTEM_HEAD} vers.o ${OBJS}
LLVM ERROR: IO failure on output stream: No space left on device
*** Error 1 in /usr/share/relink/kernel/GENERIC (Makefile:2432 'newbsd': @echo
ld -T ld.script -X --warn-common -nopie --no-mmap-output-file...)
It is also completely undocumented.
I suspect this flag was added to lld after the man page was last updated.
