Bug#954031: sbcl: Please allow building with clisp on currently unsupported architectures

[John Paul Adrian Glaubitz]

Source: sbcl
Severity: normal
Tags: patch

Hi!

In order to provide some basic level of continuous integration for
sbcl upstream, it would be great if the sbcl package could be tried
to build on any of the currently unsupported architectures using
clisp.

sbcl has partial support for alpha, hppa, mips*, ppc64 and riscv64
and if we try to build sbcl on any architecture using clisp, we will
be able to provide upstream with a build log of sbcl on any architecture
that might be supported in the future (like ppc64 and riscv64) or
was previously supported and is currently broken (like alpha and hppa).

The attached patch enables building with clisp on all unsupported
architectures.

Thanks,
Adrian

I'm working on getting SBCL buildable on Debian using CLISP. Then we get
a CI for all architectures for free which does not depend on a working
SBCL compiler being available on the FTP servers.
