[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.

gcc
* configure: Regenerate.
* configure.ac: Define TARGET_LIBC_GNUSTACK on musl.
