From ea650cae26da4a8fc04f0c4666f4dd776d0b5fc0 Mon Sep 17 00:00:00 2001 From: Ilya Lipnitskiy Date: Sun, 14 Nov 2021 21:54:25 -0800 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.
