Jakub Jelinek 0284b52ec9 elf.c (ET_DYN): Undefine and define again. 
* elf.c (ET_DYN): Undefine and define again.
	(elf_add): Add exe argument, if true and ehdr.e_type is ET_DYN,
	return early -1 without closing the descriptor.
	(struct phdr_data): Add exe_descriptor.
	(phdr_callback): If pd->exe_descriptor is not -1, for very first
	call if dlpi_name is NULL just call elf_add with the exe_descriptor,
	otherwise backtrace_close the exe_descriptor if not -1.  Adjust
	call to elf_add.
	(backtrace_initialize): Adjust call to elf_add.  If it returns
	-1, set pd.exe_descriptor to descriptor, otherwise set it to -1.

README 

The libbacktrace library
Initially written by Ian Lance Taylor <iant@google.com>

The libbacktrace library may be linked into a program or library and
used to produce symbolic backtraces.  Sample uses would be to print a
detailed backtrace when an error occurs or to gather detailed
profiling information.

The libbacktrace library is provided under a BSD license.  See the
source files for the exact license text.

The public functions are declared and documented in the header file
backtrace.h, which should be #include'd by a user of the library.

Building libbacktrace will generate a file backtrace-supported.h,
which a user of the library may use to determine whether backtraces
will work.  See the source file backtrace-supported.h.in for the
macros that it defines.

As of September 2012, libbacktrace only supports ELF executables with
DWARF debugging information.  The library is written to make it
straightforward to add support for other object file and debugging
formats.
