a235c45354 arm: libbacktrace: Check if the compiler supports __sync atomics 
Older versions of the Arm architecture lack support for __sync
operations directly in hardware and require calls into appropriate
operating-system hooks.  But such hooks obviously don't exist in a
freestanding environment.

Consquently, it is incorrect to assume during configure that such
functions will exist and we need a configure-time check to determine
whether or not these routines will work.

libbacktrace:

	* configure.ac: Always check if the compiler supports __sync
	operations.
	* configure: Regenerated.

bf406a5369 libbacktrace: avoid infinite recursion 
We could get an infinite recursion in an odd case in which a
.gnu_debugdata section was added to a debug file, and mini_debuginfo
was put into the debug file, and the debug file was put into a
/usr/lib/debug directory to be found by build ID.  This combination
doesn't really make sense but we shouldn't get an infinite recursion.

	* elf.c (elf_add): Don't use .gnu_debugdata if we are already
	reading a debuginfo file.
	* Makefile.am (m2test_*): New test targets.
	(CHECK_PROGRAMS): Add m2test.
	(MAKETESTS): Add m2test_minidebug2.
