Yes. Just like C.

Could be.
You can use the same tricks with make that have been used with C for 30
years:
$ cat defs.mk
ifndef _defs.mk
_defs.mk := 1
...
endif
If you don't even want to try reading the file at all when it's already
been included, you have to put the ifndef around the include statement:
ifndef _defs.mk
include defs.mk
endif
