Now that transparent aliases are heavily used by VMS to translate names, we shouldn't directly emit symbol name but use assemble_name.
This patch fixes some abuse.

Committed on trunk.

Tristan.

	* config/alpha/alpha.c (alpha_use_linkage): Follow transparent alias.
	(alpha_write_one_linkage): Use assemble_name to emit linkage name.
