build: Rename pic objects to _.os to support -gsplit-dwarf

We build almost everything twice, with and without -fpic. The first
as normal .o files, the second as .os files. We then use the .os pic
objects to create the shared libraries.

This doesn't work well when using -gsplit-dwarf because the object
files have the same base name. So both the file.o and file.os will
have the same file.dwo file generated. Which means the split dwarf
.dwo file is only valid for the last build object file. This breaks
various self tests when building with CFLAGS="-g -O2 -gsplit-dwarf".

Work around this by renaming the base object file name for the pic
objects by adding an _.

	* config/eu.am: Replace %.os rule to %_.os.
	* backends/Makefile.am (am_libebl_backends_pic_a_OBJECTS):
	Replace .c SOURCES with _.os OBJECTS.
	* debuginfod/Makefile.am (am_libdebuginfod_pic_a_OBJECTS):
	Likewise.
	* libasm/Makefile.am (am_libasm_pic_a_OBJECTS): Likewise.
	* libcpu/Makefile.am (am_libcpu_pic_a_OBJECTS): Likewise.
	* libdw/Makefile.am (am_libdw_pic_a_OBJECTS): Likewise.
	* libdwelf/Makefile.am (am_libdwelf_pic_a_OBJECTS): Likewise.
	* libdwfl/Makefile.am (am_libdwfl_pic_a_OBJECTS): Likewise.
	* libdwfl_stacktrace/Makefile.am
	(am_libdwfl_stacktrace_pic_a_OBJECTS): Likewise.
	* libebl/Makefile.am (am_libebl_pic_a_OBJECTS): Likewise.
	* libelf/Makefile.am (am_libelf_pic_a_OBJECTS): Likewise.

srcfiles: Handle CU names and files from split DWARF

collect_sourcefiles was still using dwarf_get_unit so would only get
the main skeleton CU DIEs. The skeleton DIE might not have a name
attribute, which is moved into the split DIE. The line table reference
is normally in the skeleton (type) unit, but might also be in the
split type unit. Use dwarf_get_units to also get the subdie and try
getting the information from that if not found in the main CU die.

This fixes the run-srcfiles-self.sh test, except for the debuginfod
part (debuginfod doesn't handle split DWARF files yet).

Also fix no-backup help comment. Add space between applicable and when.

	* src/srcfiles.cxx (options): nobackup add space between
	applicable and when.
	(collect_sourcefiles): Use dwarf_get_units, get subdie, try
	dwarf_diename and dwarf_getsrcfiles on subdie.
