* preinstall.am, shared/lpc/include/lpc-i2s.h,
	shared/startup/linkcmds.armv4, shared/startup/linkcmds.armv7: New
	files.
	* Makefile.am: Added header and linker command files intended to be
	used by every ARM BSP.
	* shared/startup/linkcmds.base: Support for EABI and ARM ELF standard.
	* shared/include/linker-symbols.h: Update due to linker command file
	changes.
	* shared/start/start.S, shared/include/start.h: Renamed entry symbol
	from start to _start to avoid namespace conflicts.  Update due to
