Bug#888877: llvm-toolchain-6.0: FTBFS on arm64: /usr/bin/ld.gold: unsupported TLSLE reloc 549 in shared code

[Emilio Pozuelo Monfort]

Source: llvm-toolchain-6.0
Version: 1:6.0~+rc1-1
Severity: serious

Hi,

There are old 6.0 binaries lying around from old llvm-toolchain-snapshot
versions, so this is RC as those binaries will prevent llvm-toolchain-6.0
from migrating to testing.
