(DBX_FINISH_SYMBOL): Rewrite and rename DBX_FINISH_STABS.
(DBX_OUTPUT_MAIN_SOURCE_DIRECTORY, DBX_OUTPUT_GCC_MARKER): Delete.
(NO_DBX_MAIN_SOURCE_DIRECTORY, NO_DBX_GCC_MARKER): Define.

* include/bits/basic_string.h (erase(size_type, size_type),
erase(iterator), erase(iterator, iterator)): Call _M_mutate
instead of _M_replace_safe, equivalent when the fourth argument
is zero and simpler.
