tools/nolibc: always disable stack protector for tests

Stack protectors need support from libc.
This support is not provided by nolibc which leads to compiler errors
when stack protectors are enabled by default in a compiler:

      CC      nolibc-test
    /usr/bin/ld: /tmp/ccqbHEPk.o: in function `stat':
    nolibc-test.c:(.text+0x1d1): undefined reference to `__stack_chk_fail'
    /usr/bin/ld: /tmp/ccqbHEPk.o: in function `poll.constprop.0':
    nolibc-test.c:(.text+0x37b): undefined reference to `__stack_chk_fail'
    /usr/bin/ld: /tmp/ccqbHEPk.o: in function `vfprintf.constprop.0':
    nolibc-test.c:(.text+0x712): undefined reference to `__stack_chk_fail'
    /usr/bin/ld: /tmp/ccqbHEPk.o: in function `pad_spc.constprop.0':
    nolibc-test.c:(.text+0x80d): undefined reference to `__stack_chk_fail'
    /usr/bin/ld: /tmp/ccqbHEPk.o: in function `printf':

    /usr/bin/ld: /tmp/ccqbHEPk.o:nolibc-test.c:(.text+0x12d4): more undefined references to `__stack_chk_fail' follow
