libpkcs11: fix multiple definition error

gcc10 default to -fno-common, which results in error:
| ../aarch64-fsl-linux/10.2.0/ld: /tmp/ccaL5AXA.o:.../libpkcs11/git-r0/git/app/pkcs11_app.c:23: multiple definition of `funcs'; /tmp/ccvGV0xB.o:.../app/utils.c:18: first defined here
| collect2: error: ld returned 1 exit status
| Makefile:66: recipe for target 'app' failed
| make: *** [app] Error 1
