+x86_64: Add support to build kexec-tools with x32 ABI
+
+Summary of changes,
+
+configure.ac: Add test for detect x32 ABI.
+purgatory/arch/x86_64/Makefile: Not use mcmodel large when
+ x32 ABI is set.
+kexec/arch/x86_64/kexec-elf-rel-x86_64.c: When x32 ABI is set
+ use ELFCLASS32 instead of ELFCLASS64.
+kexec/kexec-syscall.h: Add correct syscall number for x32 ABI.
+
+Upstream-Status: Submitted
