Xcode 7 and later have replaced the system assembler with Clang, which doesn't support stabs debug information. If there are any places where you can specify options to be used while compiling libgcc.a, try adding the -gdwarf-2 flag.
You could also try downgrading to Xcode 6.4, which still shipped with the old assembler. You can get it from https://developer.apple.com/downloads/
