glibc build error
I'm using qemu-aarch64[1], and trying to build rootfs with gcc-4.9.0,
glibc-2.17, binutils-2.24.51.0.1
following commit[2] result in un-usable glibc (2.17), I haven't trace to the
root cause, but detail error can be seen in "glibc.error"[4]
btw, I'm using "git bisect" to find this commit[2]. and also tested passed with
latest commit[3], but with this commit[2] reverted.
