[Buildroot] ARC toolchain build failure

[Thomas Petazzoni]

Hello,

When trying to build an ARC toolchain with the following defconfig:

BR2_arcle=y
BR2_archs38=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_KERNEL_HEADERS_4_14=y
BR2_BINUTILS_VERSION_2_30_X=y
BR2_GCC_VERSION_8_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_HOST_GDB=y
BR2_INIT_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_GDB=y
# BR2_TARGET_ROOTFS_TAR is not set

It fails with:

/opt/arcle-hs38--glibc--bleeding-edge-2018.05-1/lib/gcc/arc-buildroot-linux-gnu/8.1.0/../../../../arc-buildroot-linux-gnu/bin/ld: /opt/output/build/glibc-arc-2018.03-rc2/build/iconvdata/libKSC.so symbol number 14 references nonexistent SHT_SYMTAB_SHNDX section

Are you aware of this issue ? Any fix ?

Thanks!
