-r is understood by gcc but not by clang, anyway its a linker option so
pass it straight to linker by using -Wl explicitly

When run "kexec" in powerpc board, the kexec has a limit that
the kernel text and bss size must be less than 24M. But now
some kernel size exceed the limit. So we need to change the limit,
else will get the error log as below:

my_load:669: do
Could not find a free area of memory of 0x12400 bytes...
Could not find a free area of memory of 0x13000 bytes...

If the GCC's stack protection is enabled by default, the purgatory will
also be built with this option. But it makes no sense to enable this
for the purgatory code, and would cause error when we are trying to
relocate the purgatory codes because symbol like __stack_chk_fail is
unresolved. Instead of disabling this for some archs specifically,
disable it for all the archs.

Add autoconf test for detect when build is x32 ABI this enables to
test into purgatory Makefile to avoid use -mcmodel=large flag in CC.

Add ELFCLASS read and syscall number into kexec, see patch.
