[PATCH] x86 boot enhancements, link enhancements 2/11

[Eric W. Biederman]

#2  2.5.8.boot.vmlinuxlds
============================================================
- i386/Makefile remove bogus linker command line of -e stext
- Fix vmlinux.lds so vmlinux knows it loads at 0x100000 (1MB)
- Fix vmlinux.lds so we correctly use startup_32 for our entry point
- Make startup_32 global
