[ARM] Fix warning cannot find thumb start symbol

In case params.thumb_entry_symbol has its default NULL value, using it
to print a warning in gld${EMULATION_NAME}_finish results in a crash.

Use h->root.string instead which either points to
params.thumb_entry_symbol name or to entry_symbol name.

	* emultempl/armelf.em (gld${EMULATION_NAME}_finish): Use the right
	symbol name in case of warning.
