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

../misc/sys/cdefs.h:81:62: note: in definition of macro ‘__NTH’

| ^~~
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.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

This one tests for BZ#23907 where the double free
test didn't check the tcache bin bounds before dereferencing
the bin.
[BZ #23907]
* malloc/tst-tcfree3.c: New.
* malloc/Makefile: Add it.
