Well, I mean, can you build some of libgcc's object files with Clang and
others with GCC? Hint: Just build everything with GCC. Afterwards, go
into the object directory, rm some of the .o files and make CC=3Dclang.
Since OOo is a C++ application, I suspect the unwind-related object
files to be the culprit.
