Here is the test I've done on my FreeBSD (8-BETA3) :

elbarto@sonic> pwd
/usr/home/elbarto/test
elbarto@sonic> ls -R
Makefile        test1

./test1:
Makefile
elbarto@sonic> cat Makefile 
all:
@echo test
elbarto@sonic> cat test1/Makefile 
all:
@echo test1
elbarto@sonic> make -C test1 -f ./Makefile 
test1
elbarto@sonic> make -C test1 -f `pwd`/Makefile
test
elbarto@sonic> make -f ./Makefile -C test1
test1
elbarto@sonic> make -f `pwd`/Makefile -C test1
test
elbarto@sonic> 

So the -C argument is done before opening the Makefile.
