    [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.
