[RFA] clean-up for sym_read mainline flag (2/2)

[Tristan Gingold <gingold@adacore.com>]

Hi,

dwarf_build_psymtabs is always called with mainline=0 (it was not in
machoread.c but a tiny change fixed that).
As a consequence, this parameter can be removed.

No regression on linux x86-64.

(More to follow...)

Tristan.

	* symfile.h (dwarf2_build_psymtabs): Remove mainline parameter in
	prototype.
	* dwarf2read.c (dwarf2_build_psymtabs): Remove mainline paramter in
	definition, simplify code assuming it is always 0.
	* coffread.c (coff_symfile_read): Adjust call.
	* elfread.c (elf_symfile_read): Ditto.
	* machoread.c (macho_symfile_read): Explicitely calls
	init_psymbol_list if mainline is set.
