use -lgcc if LINK_EH_SPEC is defined and -lgcc_s -lgcc if not.
If none of the above switches are passed, use -lgcc -lgcc_eh.
(init_spec): If LINK_EH_SPEC is defined, prepend it to link_spec.
* mklibgcc.in: Don't include LIB2ADDEH objects into libgcc.a if
creating libgcc_s.so, put them into separate libgcc_eh.a instead.

Because the longest linear sequence we are trying to locate within the

incoming LINEAR array can be interspersed with (high valued) erratic
|
|
|
|

entries. We construct a chain indicating the sequenced entries.
|
|
|
|
|
To avoid having to allocate this chain, we overlay it onto the space of
|
|
|
|
|
the ERRATIC array during construction. A final pass iterates over the
|
|
|
|
|
chain to determine what should be placed in the ERRATIC array, and
|
|
|

what is the linear sequence. This overlay is safe from aliasing. */
