As pointed out in a libc-alpha thread [1], the misc/tst-ofdlocks-compat
may fail in some specific Linux releases. This patch adds a comment
along with a link to discussion in the test source code.
No changes are expected.
* sysdeps/unix/sysv/linux/tst-ofdlocks-compat.c: Add a comment about
a kernel issue which lead to test failure in some cases.

[BZ #23036]
#define PREPARE do_prepare
+/* Linux between 4.13 and 4.15 return EOVERFLOW for LFS OFD locks usage
+ in compat mode (non-LFS ABI running on a LFS default kernel, such as
+ i386 on a x86_64 kernel or s390-32 on a s390-64 kernel) [1]. This is
+ a kernel issue because __NR_fcntl64 is the expected way to use OFD locks
+ (used on GLIBC for both fcntl and fcntl64).
