Plain gallium, as per below.

../../../../src/gallium/auxiliary/.libs/libgallium.a(lp_bld_misc.o):
In function `llvm::RTDyldMemoryManager::getSymbolAddress(std::__cxx11::basic_string<char,
std::char_tra
its<char>, std::allocator<char> > const&)':
/usr/local/include/llvm/ExecutionEngine/RTDyldMemoryManager.h:87:
undefined reference to
`llvm::RTDyldMemoryManager::getSymbolAddressInProcess(std::__cxx11::basic_string<ch
ar, std::char_traits<char>, std::allocator<char> > const&)'
/usr/local/include/llvm/ExecutionEngine/RTDyldMemoryManager.h:87:
undefined reference to
`llvm::RTDyldMemoryManager::getSymbolAddressInProcess(std::__cxx11::basic_string<ch
ar, std::char_traits<char>, std::allocator<char> > const&)'

An identical symbol with different signature is provided by the static
lib and header:

$ objdump -CtT libLLVMRuntimeDyld.a | grep
"llvm::RTDyldMemoryManager::getSymbolAddressInProcess"
... 0000000000000149
llvm::RTDyldMemoryManager::getSymbolAddressInProcess(std::string
const&)

$ grep getSymbolAddressInProcess .../include/
RTDyldMemoryManager.h:  static uint64_t
getSymbolAddressInProcess(const std::string &Name);

And in the LLVM 3.8 case (which works like a charm):

$ objdump -CtT libLLVMRuntimeDyld.a | grep
"llvm::RTDyldMemoryManager::getSymbolAddressInProcess"
...0000000000000181
llvm::RTDyldMemoryManager::getSymbolAddressInProcess(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)

$ grep getSymbolAddressInProcess .../include/
RTDyldMemoryManager.h:  static uint64_t
getSymbolAddressInProcess(const std::string &Name);

It smells like partial/incomplete build with the C++11 ABI, but trying
to untangle the lot is quite time consuming.
