malloc: Fix tst-tcfree3 build csky-linux-gnuabiv2 with fortify source
With gcc 13.1 with --enable-fortify-source=2, tst-tcfree3 fails to
build on csky-linux-gnuabiv2 with:
../string/bits/string_fortified.h: In function ‘do_test’:
../string/bits/string_fortified.h:26:8: error: inlining failed in call
to ‘always_inline’ ‘memcpy’: target specific option mismatch
26 | __NTH (memcpy (void *__restrict __dest, const void *__restrict
__src,
| ^~~~~~
../misc/sys/cdefs.h:81:62: note: in definition of macro ‘__NTH’
81 | # define __NTH(fct) __attribute__ ((__nothrow__ __LEAF)) fct
| ^~~
tst-tcfree3.c:45:3: note: called from here
45 | memcpy (c, a, 32);
| ^~~~~~~~~~~~~~~~~
Instead of relying on -O0 to avoid malloc/free to be optimized away,
disable the builtin.
