* Support for i386-sysv.
configure.in: check for i386-*-sysv* and i386-*-sco*.
i386coff.sc-sh: rewrote to support SVR3 by default.
ldctor.c (find_constructors): preserve stat_ptr.
ldlang.c (wild_doit): initialize vma and size of new output
section to corresponding input section. This is required for
shared library support.
(lang_size_sections): don't modify vma and size of sections which
are never loaded (for shared libraries).
ldwrite.c (copy_and_relocate): copy the contents of any section
which has contents, not just sections which are loaded (for shared
libraries).
