+Upstream-Status: Backport [https://github.com/OP-TEE/optee_os/pull/5474]
+
+binutils ld.bfd generates one RWX LOAD segment by merging several sections
+with mixed R/W/X attributes (.text, .rodata, .data). After version 2.38 it
+also warns by default when that happens [1], which breaks the build due to
+--fatal-warnings. The RWX segment is not a problem for the TEE core, since
+that information is not used to set memory permissions. Therefore, silence
+the warning.
