[lto][patch] Use elf_strptr in the plugin

["Rafael Espindola" <espindola at google dot com>]

This patch is just a cleanup that replaces get_string_table with elf_strptr.

2008-09-09  Rafael Avila de Espindola  <espindola@google.com>

	* lto-plugin.c (get_string_table): Remove.
	(get_section): Use elf_strptr instead of get_string_table.

Cheers,
