Change the linker's heuristic for computing the entry point for binaries so that shared libraries default to an entry point of 0.

	* ldlang.c (lang_end): When computing the entry point, only
	try the start address of the entry section when creating an
	executable.
	* ld.texi (Entry point): Update description of heuristic used to
	choose the entry point.
	testsuite/ld-alpha/tlspic.rd: Update expected entry point address.
