基于新版dd-wrt的arm架构的musl libc编译失败

[harleylg]

我的路由器是R6300v2，编译用的是dd-wrt的新版toolchain：http://download1.dd-wrt.com/dd-wrtv2/downloads/toolchains/toolchains.tar.xz （6月15日版本），里面一大堆toolchain实在不知道该用哪个，dd的文档实在是一坨屎，想用OpenWrt的toolchain，不过dd最近似乎都用musl libc，OpenWrt用的还是uClibc。

如果用toolchain-arm_cortex-a9_gcc-4.8-linaro_musl-1.1.5_eabi编译（这个似乎是官方使用的toolchain，论坛里面几篇帖子提及toolchain的似乎都用这个），会报以下错误：

make  all-recursive

尝试用toolchain-arm_cortex-a9+neon_gcc-4.8-linaro_musl-1.1.2_eabi编译，configure失败。我用的命令是：CC=arm-linux-gcc CXX=arm-linux-g++ AR=arm-linux-ar RANLIB=arm-linux-ranlib ./configure --prefix=/home/harley/packages/chinadns --host=arm-linux

尝试用toolchain-arm_mpcore+vfp_gcc-4.8-linaro_musl-1.1.4_eabi编译，则报告以下错误：

用 git master 版的代码编译试试。

master的一次通过，用的toolchain是toolchain-arm_cortex-a9_gcc-4.8-linaro_musl-1.1.5_eabi
