Log Message:
make: fix null pointer when including empty file (since 2022-01-01)
Calling malloc(0) may return a null pointer, but callers of bmake_malloc
do not expect that.
Reported by Chris Pinnock, found by cross-compiling NetBSD on OpenBSD,
where tools/groff creates Makefile.dep files of size 0.
