A little portability patch for BFD

[Michael Sokolov]

Hi there,

A small portability patch in BFD for K&R C compilers. While compiling under
4.3BSD for the m68k-elf target, I bumped into these two problems:

* concat_filename() in dwarf2.c concatenates two string literals in one place,
which the C preprocessor on 4.3BSD didn't like.

* ieee_get_symtab() in ieee.c initializes a struct with a union inside it in a
way that the K&R C compiler didn't like. As far as I can tell initializing that
last member isn't necessary at all and I took it out.

The patch is below. Is it OK?

	* dwarf2.c (concat_filename): avoid string literal concatenation.

	* ieee.c (ieee_get_symtab): avoid union-in-a-struct initialization that
	K&R C compilers choke on.
