[OSSTEST PATCH] ts-xen-build-prep: Grab newer NASM version, to build OVMF

[Anthony PERARD]

Recent versions of OVMF now need a version of NASM that is newer
than the one available on Debian oldstable/buster. They want to use
NASM 2.15.05 [1], which is available in Debian stable/bullseye. The
need to use a newer version started with d3febfd9ade3 ("MdePkg:
Replace Opcode with the corresponding instructions.").

There is no backport package available but the nasm package from
Debian Bullseye can easily be installed on Buster as it has few
dependencies and are already satisfied.

A flight with my change:

(ignore the failing "libvirt-build" jobs which shouldn't be part
of the flight ;-) )

I think this is likely too fragile, what will happen when the package
gets bumped to a newer version?

I think we need to store a local copy in osstest and install from
there instead of trying to fetch from the upstream Debian mirror.

I guess we could use something similar to DebianExtraPackages?

DebianExtraPackages_build_$arch_$suite nasm_2.15.05-1_$ho->{Arch}.deb

And fetch those using the some_extradebs method.

Thanks, Roger.

I think this is a quite fine bodge.

I don't think this use of /tmp is very nice.  ts-xen-build-prep runs
with the host all to itself, so I think you can use /root ?

Yes, I think this is better.
