Latest clang from trunk causes a linker error with '-mmacosx-version-min=' <=
10.5 given.
Xcode clang works as expected (note: this only happens for x86_64).

$ echo "int main(){return 0;}" | ~/llvm-trunk/bin/clang -xc
-mmacosx-version-min=10.5 -arch x86_64 -
ld: symbol index out of range file
'/var/folders/yv/43njmxj17k7gv_04z6m21krm0000gn/T/--fab1f1.o' for architecture
x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

$ ld -v
