Maybe clarify one little bit about xshndx:

xshndx also should be zero (SHN_UNDEF) when sym->st_shndx !=
SHN_XINDEX. This implementation doesn't not check that condition
however (you are allowed to store a non-zero value in the xindex, but
that would result in an inconsistent ELF.)

Maybe that is too pedantic though. So you decide :)
