+ltp: fix build failure with glibc 2.43
+
+glibc 2.43 added native openat2() support for the first time. This
+caused compatibility issues with LTP's internal openat2 definitions
+in lapi/openat2.h. LTP's configure detects glibc's openat2() and
+sets HAVE_OPENAT2=1, causing lapi/openat2.h to skip its own
+definitions of struct open_how, RESOLVE_* constants and the openat2()
+wrapper, resulting in a build failure.
+
+Undef HAVE_OPENAT2 in lapi/openat2.h to force LTP to always use its
+own internal definitions. The proper fix will be investigated and
+submitted upstream ASAP.
+
+Upstream-Status: Inappropriate [oe-core specific]
