From 25abbb9249685c8519d06e1d98cd6803568b6eb7 Mon Sep 17 00:00:00 2001 From: Ilya Lipnitskiy Date: Thu, 2 Dec 2021 15:47:11 -0500 Subject: [PATCH] [PATCH v2] 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.
