PR ld/11426 am33, arm, ia64

[Alan Modra <amodra at gmail dot com>]

I think almost all of the linux targets need no changes to the default
linux HOSTING_CRT0.  Certainly any edits that replace specs.*" should
go;  Since 2005-07-19 the default linux HOSTING_CRT0 hasn't looked at
specs.  That just leaves am33, arm and ia64.  Can someone with access
to those targets test this patch before I commit?

	PR ld/11426
	* configure.host (many linux targets <HOSTING_CRT0>): Remove edits.
	(m68*-motorola-sysv <HOSTING_LIBS>): Use here doc, not echo.
