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.

g-wrap-config(1)					      General Commands Manual						  g-wrap-config(1)

NAME
g-wrap-config - script to get information about the installed version of G-Wrap SYNOPSIS
g-wrap-config [ --version ] [ --c-compile-args LANG | --c-link-args LANG | --guile-module-directory ] DESCRIPTION
g-wrap-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link progams, libraries, and plugins that use G-Wrap. However, since G-Wrap 1.9, this tool has been deprecated in favor of pkg-config(1). New code should use the g-wrap-2.0-guile pkg-config module, g-wrap-config only exists for compatibility reasons. OPTIONS
--c-compile-args LANG Print the compiler flags that are necessary to compile a program or library that uses the G-Wrap language binding for LANG. --c-link-args LANG Print the linker flags that are necessary to link a program that uses the G-Wrap language binding for LANG. --version Prints the currently installed version of G-Wrap on standard output. EXAMPLES
gcc -o main.o $(g-wrap-config --c-compile-args guile) main.c is how you might use g-wrap-config to compile a C source file for an executable program. gcc -o my_app $(g-wrap-config --c-link-args guile) main.o util.o is how you might use g-wrap-config to link compiled objects into an executable program. AUTHOR
G-Wrap has been written by Andreas Rottmann, Rob Browning and Christopher Lee. This manual page was written by Andreas Rottmann, originally for the Debian Project. G-Wrap 1.9 2005-05-01 g-wrap-config(1)
