[Cin] Build from git

[Andrea paz]

Sorry, I didn't even realize to apply the patches after autogen.sh...

Still error; I attach cin5.log and config.log

NOTE:
Reading the config.log I noticed 2 entries that probably have nothing
to do with the problems encountered, but are 2 critical things in my
system:

1- in config.log you refer to ROCM; my video card on Arch has many
problems with rocm.
2- Arch recently introduced experimental support for LTO in gcc.
Fedora and others have had it for years, but Arch may have problems
and instability.
