+ ~~~~~~~~~~^~~~~~
+
+Build tested with Yocto for ARM, AARCH64, X86, X86_64, PPC, MIPS, MIPS64
+with -O, -O1, -Os.
+For soft-fp ARM it needs one more fix for -O1:
+https://sourceware.org/ml/libc-alpha/2018-09/msg00300.html
+For AARCH64 it needs one more fix in locale for -Os.
+
+ [BZ #23716]
+ * sysdeps/ieee754/dbl-96/e_jnl.c: Fix build with -O
+ * sysdeps/ieee754/ldbl-96/e_jnl.c: Likewise.
+ * sysdeps/ieee754/ldbl-128/e_jnl.c: Likewise.
+ * sysdeps/ieee754/ldbl-128ibm/e_jnl.c: Likewise.
+
+Work around the issue instead of removing -O like we do with
