Hi Simon, I did more testing and found that the patch causes a fail when try to compile with zlib and other arch not x86_64, it's related to AC_EGREP_CPP needs previous AC_PROG_CC. I sent a patch for that, http://lists.infradead.org/pipermail/kexec/2015-April/013554.html Sorry for the problems that i may have caused.
