[Buildroot] mips64/uclibc toolchain issue

[Thomas Petazzoni]

Hello,

For the autobuilders, I've tried to build the following toolchain
configuration:

BR2_mips64el=y
BR2_mips_64r2=y
BR2_MIPS_NABI64=y
# BR2_MIPS_SOFT_FLOAT is not set
BR2_TOOLCHAIN_BUILDROOT_INET_RPC=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_PTHREAD_DEBUG=y
BR2_BINUTILS_VERSION_2_23_X=y
BR2_GCC_VERSION_4_8_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_INIT_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
# BR2_TARGET_ROOTFS_TAR is not set

and it fails with:

Could you have a look ?
