Linux-2.4 can be compiled with tinycc compiler:
- AoT with contained Kbuild.sh
- JiT with https://bellard.org/tcc/tccboot.html

Kbuild.sh contains further comments.
linux-2.4.37 folder contains kernel sources with all necessary patches applied
from patches/kernel folder.

A recent tinycc compiler is required, tested with mob branch commit
085e029f08c9b0b57632703df565efdbe2cd0c7f november 2024.

Currently it is recommended to execute Kbuild.sh on a native x86 build host
instead of using tcc as cross-compiler accross different architectures, because
unknown side-effects could not be confirmed which occured when residing on an
aarch32 buildhost for testing compilation towards x86 target.

With a local test setup the patched linux-2.4.37.11 sources compiled, linked
and too booted successfully including USB, SMP, O1/NPTL, grsecurity support.

With plans for a complete i586-tcc-linux-musl.iso distribution this project
will be incorporated into system integration gradually; musl-libc 1.1.24
sanitized for linux-2.4 ABI together with a complete system profile including
important development utilities are supported already.
