+Subject: [PATCH] configure: define TARGET_LIBC_GNUSTACK on musl
+
+musl only uses PT_GNU_STACK to set default thread stack size and has no
+executable stack support[0], so there is no reason not to emit the
+.note.GNU-stack section on musl builds.
+
+[0]: https://lore.kernel.org/all/20190423192534.GN23599@brightrain.aerifal.cx/T/#u
+
+gcc/ChangeLog:
+
+	* configure: Regenerate.
+	* configure.ac: define TARGET_LIBC_GNUSTACK on musl
