* 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).

# Linker script for 386 COFF. This works on SVR3.2 and SCO Unix 3.2.2.
# .data2 handles SCO, which uses two data sections.
