libabigail/configure.ac
Sinny Kumari 388f990681 Check if EM_AARCH64, EM_TILEPRO and EM_TILEGX macros are defined in elf.h 
Macros EM_AARCH64, EM_TILEPRO and EM_TILEGX were defined in diffrent
commits and release of glibc which is glibc 2.16 and 2.17 in elf/elf.h
file. Compiling libabigail was failing duing to undefined behaviour of
above macros in older glibc release. To solve it, configure.ac checks
whether these macros are defined or not and sets accordinlgy
HAVE_EM_AARCH64_MACRO, HAVE_EM_TILEPRO_MACRO and HAVE_EM_TILEGX_MACRO
macros.

	* config.h.in: Generated autoheader by configure.ac
	for added macros
	* configure.ac: Defining HAVE_EM_AARCH64_MACRO,
	HAVE_EM_TILEPRO_MACRO and HAVE_EM_TILEGX_MACRO to check
	whether EM_AARCH64, EM_TILEPRO and EM_TILEGX macros are defined
	in elf.h or not
	* src/abg-dwarf-reader.cc (e_machine_to_string): Look for
	EM_AARCH64, EM_TILEPRO and EM_TILEGX macros only
	if they are defined in elf.h
