Subject: [PATCH v2] configure: define TARGET_LIBC_GNUSTACK on musl
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=25abbb9249685c8519d06e1d98cd6803568b6eb7;p=test_jj.git

[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.
