In style of linked lists, instead of declaring symbols for boundaries of getopt options array in the linker script, declare corresponding sections and retrieve the boundaries via static inline functions. Without this clang's LTO produces binary without any getopt options, because for some reason it thinks that array is empty (start and end symbols are at the same address).
