to add the 0x10 and 0x18 descriptors for Linux.
This will not work when the existing GDT is in ROM.
Change the code to set up a new GDT in what we know to be
RAM.
Tested by booting a linux payload. The main reason this works
is that Linux almost immediately loads its own GDT and then
segment registers. This GDT is a very temporary bridge.
Note that none of this change used to be necessary; the coreboot
GDT was originally compatible with Linux (ca 2000);
then Linux changed.

Because earlier versions of debian set /dev as a standard tmpfs
filesystem, that was a simple place to build. Now, this has been
changed and /dev isn't a standard tmpfs that will grow to 50% of
memory. It's a fixed, very small size, and can no longer even be
resized.
Because of this, create a new directory to build in and add it to
/etc/fstab. Mount it when the container is started.
As long as we're at it, make the other build directories (ccache
and slave-root/workspace) tmpfs as well. The builders we're using now
have plenty of memory, so don't write any of the files to disk.
Update the Makefile to get rid of all references to ccache directory.
