This is a rare question indeed for this forum.

What are you trying to do???? And why???????

You are missing the point here my friend. You downloaded the entire source code for your O/S of choice so you have the source code of the C compiler, the source code of all shared libraries, the source code for the shells, et al. You do not have any executables!!!

So the question that you are really asking is:
Q: How do I compile a compiler without a compiler?
A: You need to 'seed' the operation via a closely related Unix/Linux version. Install a closely related foreign version and compile the entire toolchain first. Having generated your toolchain this way, you then need to compile the toolchain AGAIN using the tools that you just generated because, for example, all your libraries will have been created cross-compiled. To get them pure you need to do it all a third time.

Once you've got a complete toolchain you can begin to compile your kernel (bespoke or not, as your choice). When the kernel is created you can install grub and boot your own kernel. Then you can continue to create all other application and things.

So, what are you trying to do? Compiling your kernel can take hundreds of hours at 100% CPU. Then you test it, realize it's wrong, and have to do it all again. It's very difficult to create bespoke O/S for multi-nationals, public services, defense contractors, etc which I know to my cost. I do it all the time. You also need an extensive knowledge of O/S internals so it's not an easy occupation.

NAME
archive - Usenet article archiver SYNOPSIS
archive [ -a archive ] [ -f ] [ -i index ] [ -m ] [ -r ] [ input ] DESCRIPTION
Archive makes copies of files specified on its standard input. It is normally run either as a channel feed under innd(8), or by a script before expire(8) is run. Archive reads the named input file, or standard input if no file is given. The input is taken as a set of lines. Blank lines and lines starting with a number sign (``#'') are ignored. All other lines should specify the name of a file to archive. If a filename is not an absolute pathname, it is taken to be relative to /var/spool/news. Files are copied to a directory within the archive directory, /var/spool/news/news.archive. The default is to create a hierarchy that mim- ics the input files; intermediate directories will be created as needed. For example, the input file comp/sources/unix/2211 (article 2211 in the newsgroup comp.sources.unix) will be copied to /var/spool/news/news.archive/comp/sources/unix/2211. OPTIONS
-a archive If the ``-a'' flag is used then its argument specifies the directory to archive in instead of the default. -f If the ``-f'' flag is used, then all directory names will be flattened out, replacing the slashes with periods. In this case, the file would be copied to /var/spool/news/news.archive/comp.sources.unix/2211. -i If the ``-i'' flag is used, then archive will append one line to the specified index file for each article that it copies. This line will contain the destination name and the Message-ID and Subject headers. -m Files are copied by making a link. If that fails a new file is created. If the ``-m'' flag is used, then the file will be copied to the destination, and the input file will be replaced with a symbolic link pointing to the new file. -r By default, archive sets its standard error to /var/log/news/errlog. To suppress this redirection, use the ``-r'' flag. EXIT STATUS
If the input is exhausted, archive will exit with a zero status. If an I/O error occures, it will try to spool its input, copying it to a file. If there was no input filename, the standard input will be copied to /var/spool/news/out.going/archive and the program will exit. If an input filename was given, a temporary file named input.bch (if input is an absolute pathname) or /var/spool/news/out.going/input.bch (if the filename does not begin with a slash) is created. Once the input is copied, archive will try to rename this temporary file to be the name of the input file, and then exit. EXAMPLES
A typical newsfeeds(5) entry to archive most source newsgroups is as follows: source-archive :!*,*sources*,!*wanted*,!*.d :Tc,Wn :/usr/lib/news/bin/archive -f -i /usr/spool/news/news.archive/INDEX HISTORY
