[PATCH next v2 3/3] CI: use coreboot mirror for GNU dependencies of coreboot

[Quentin Schulz <foss+uboot@0leil.net>]

From: Quentin Schulz <quentin.schulz@cherry.de>

coreboot buildgcc script downloads GNU dependencies from GNU FTP server.
For some reason, this is also as unreliable as their git main server.
There's no option to use a GNU mirror (and I'm not even sure if there's
one for FTP), so we simply pass --mirror to the buildgcc script via the
BUILDGCC_OPTIONS variable so that it makes use of coreboot's mirror.
Hopefully, this proves more reliable than GNU original FTP server.
