Darwin, Simplify headers 1/5 : Move LINK_GCC_C_SEQUENCE_SPEC [NFC].
There is no need to make the LINK_GCC_C_SEQUENCE_SPEC conditional on
configuration parameters, it is adequately conditionalized on the
macosx-version-min.
gcc/ChangeLog:
* config/darwin10.h (LINK_GCC_C_SEQUENCE_SPEC): Move from
here...
* config/darwin.h (LINK_GCC_C_SEQUENCE_SPEC): ... to here.
