Repro script and log
I tried building LLVM trunk with the following CMake config:
```
cmake $SOURCE -G Ninja \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=$TARGET \
-DLLVM_LINK_LLVM_DYLIB=On \
-DLLVM_ENABLE_LTO=On \
-DLLVM_ENABLE_ASSERTIONS=On \
-DLLVM_TARGETS_TO_BUILD=X86
```
However, the process crashed at linking tblgen with numerous errors, including
the following four:
/usr/bin/ld: error: lib/libLLVMSupport.a: no archive symbol table (run ranlib)
/usr/bin/ld: error: lib/libLLVMTableGen.a: no archive symbol table (run ranlib)
/usr/bin/ld: error: lib/libLLVMSupport.a: no archive symbol table (run ranlib)
/usr/bin/ld: error: lib/libLLVMDemangle.a: no archive symbol table (run ranlib)
... followed by an uncountable number of undefined references.
I'm using llvm-3.8's clang/clang++ and GNU gold 1.14 from binutils 2.28 in this
build.
I'm attaching my repro script and full log
(gathered as `bash repro.sh 2>&1 | tee repro.log`)</pre>
