libbacktrace: handle MOREDATA correctly without debug info

Browse Source 
Based on patch from Andi Kleen.

	* elf.c (elf_nodebug): Handle state->moredata.
	* fileline.c (backtrace_syminfo_to_full_callback): Remove
	incorrect comment about MOREDATA.
	(backtrace_syminfo_to_full_callback_moredata): New function.
	* internal.h (backtrace_syminfo_to_full_callback_moredata):
	Declare.
	* strippedtest.c: New file.
	* configure.ac: check whether objcopy supports --strip-debug.
	* Makefile.am (strippedtest_SOURCES): New variable.
	(strippedtest_CFLAGS, strippedtest_LDFLAGS): Likewise.
	(strippedtest_LDADD): Likewise.
	(check_PROGRAMS): Add strippedtest.
	(MAKETESTS): Add strippedtest_stripped
	(%_stripped): New rule.
	* configure, Makefile.in: Regenerate.
