+Subject: [PATCH] dirent: conditionalize dirent assert based on dirent64
+ existence
+
+>=musl-1.2.4 doesn't define dirent64 and its LFS friends as its "native"
+functions are already LFS-aware.
+
+Check for dirent64 in meson.build and only assert if it exists.
+
+Bug: https://bugs.gentoo.org/905900
