For the same reason we don't link kernel against libgcc?
I.e. just a matter of taste. There are two camps: those who
argue against libgcc, and those who argue for libgcc.

Hey! You were in this thread! :-)

Purgatory is just a small (tiny) piece of code that runs
between kernels. Whether use libgcc or not, personally, I have
no strong opinion. Kexec didn't use it, so we kept it the same
way.

Thanks,
