patches: werror: add 1.3134-2.2.7a-gnu (hack)20240315

The ancient fork of libtool in binutils/gdb/gcc doesn't know about most
of these flags (the fork mostly exists because of divergence in what --with-sysroot
means but there's some other unknown/undocumented differences too).

I'm kind of cheating here because this isn't split up per-type, which I should
probably go and do, but it feels silly to spend time on it given it's solely
for 3 packages...

Anyway, for this, we now get proper colour and -Werror and such with LTO.
