Test using Cygwin:

0:BLACKBOX:~/test$ cat Makefile.u8
対象:
        touch $@
0:BLACKBOX:~/test$ od -t x1 Makefile.u8
0000000 e5 af be e8 b1 a1 3a 0a 09 74 6f 75 63 68 20 24
0000020 40 0a
0000022
0:BLACKBOX:~/test$ make -f Makefile.u8
touch 対象
0:BLACKBOX:~/test$ ls -lt | head -3
total 573
-rw-r--r--  1 kaz kaz      0 Sep 29 09:56 対象
-rw-r--r--  1 kaz kaz     18 Sep 29 09:55 Makefile.u8
0:BLACKBOX:~/test$

When I open the dire^H^H^H^Hfolder in Windows Explorer,
the 対象 name correctly appears, too. Thus, native Windows understands
the name properly.

I suspect there may be some caveats, including the manner in which
GNU Make has been ported, using what environment.
