Print last logfile after encountering an error

[kpcyrd]

I encountered an error and had trouble figuring out what went wrong because the script just failed with "make indicated an error":

Running ['./scripts/feeds', 'install', '-a'] in /asdf/rebuild

After catting all files in the log folder and going through the output I found the root cause, but maybe this should've been available on stdout of the rebuild log?

checking for mkfifo... yes
checking whether mkfifo rejects trailing slashes... yes
checking whether mknod can create fifo without root privileges... configure: error: in `/asdf/rebuild/build_dir/host/tar-1.32':
configure: error: you should not run configure as root (set FORCE_UNSAFE_CONFIGURE=1 in environment to bypass this check)
See `config.log' for more details

Thanks!

I somewhat disabled verbose logs as it slows down the CIs, it's just massive amounts of text. I think I could implement something like printing the error.txt file so people know where to look specifically.

Does this solve the issue? #6
