Workaround a koji build failure

with below CFLAGS, kexec-tools can not build:
--specs=/usr/lib/rpm/redhat/redhat-annobin-cc1

segfault happened while strip the purgatory:

Reported rhbz1520805, a binutils bug is pending to be fixed,
Will revert this once binutils bug is fixed and usable in koji build system.
