[poky] Workaround for fetching files

[Arno]

My question: Can I download some files that gives errors fetching during the build process and a new bitbake will recognise it? Probably it is not so simple, due to all this fancy stuff with timestamps .....
But - is there a way?

I am in a company network, due to strict rules I am often faced with problems fetching file.
So I am not able to use git protocol, most http(s) is the workaround.

Sometimes I can access files by browser (sources.openembedded.org/git2_git.yoctoproject.org.yocto-kernel-tools.git.tar.gz)
but the yocto build process can't and gives errors.

Either there is a problem with certificates (and even "export GIT_SSL_NO_VERIFY=1" before calling bitbake doesn't help") or there is "No route to host"

ERROR: Fetcher failure: Fetch command failed with exit code 128, output:
fatal: unable to access 'https://github.com/Xilinx/linux-xlnx.git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
