Traditionally, it has been defined in crtbegin.o, which is typically provided by libgcc or as part of the C library on some systems. However, but there's no principled reason for it to be there. We optionaly define this symbol, which can be used on platforms that don't provide __dso_handle in crtbegin.o or which don't use crtbegin.o at all.
