From: Arnaldo Carvalho de Melo <[email protected]> In older distros we were not including our copies of unistd_{32,64}.h, as we were relying on the system's asm/unistd.h, and a log time ago the files to be included were asm-{x86_64,i386}/unistd.h.
Fix it by also carrying a copy of asm/unistd.h, that will be the same as in modern distros and will allow us to provide missing __NR_setns, for instance, in older distros.
