Output from "make > dwarf_error.txt 2>&1" after a failing build

Since Wednesday or Thursday last week, builds have failed on Cygwin with error
messages like the following:

/usr/lib/gcc/i686-pc-cygwin/4.3.2/../../../../i686-pc-cygwin/bin/ld: Dwarf
Error: found dwarf version '8242', this reader only handles version 2
information.
/c/temp/llvm-svn/Debug/lib/LLVMXCore.o:XCoreTargetMachine.cpp:(.rdata$_ZTVN4llvm18XCoreTargetMachineE[vtable
for llvm::XCoreTargetMachine]+0x4c): undefined reference to
`llvm::LLVMTargetMachine::addPassesToEmitMachineCode(llvm::PassManagerBase&,
llvm::MachineCodeEmitter&, llvm::CodeGenOpt::Level)'

I'm attaching the make output from building again after a failure.

I am currently running revision 70826, but have had autobuild running since
around 15:00 UTC on April 30. No builds have succeeded. The last revision that
I know did not have this problem was 70374. Current svn info output:
