From c8e68150bfe2578ce7b0681465d08c5f01823db4 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 19 Sep 2016 12:59:32 -0700 Subject: [PATCH] toolchain: Rework external toolchain libc selection Make it a choice menu which offers the 3 C libraries we know about: glibc, uClibc and musl. While at it, make it possible for the external toolchain libc to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages to conditionally include specific CFLAGS (e.g: iproute2). Because USE_GLIBC et al. can now be selected by external toolchains, we need to restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN. While at it, make musl the default C library for external toolchain to match the internal toolchain.
