make symtab::dirname const

Browse Source 
This makes symtab::dirname const and updates one spot to avoid an
intermediate constless result.

2013-12-06  Tom Tromey  <tromey@redhat.com>

	* buildsym.c (end_symtab_from_static_block): Use obstack_copy0.
	* symtab.h (struct symtab) <dirname>: Now const.
