Unable to compile on raspberry pi (again)

[Sod-Almighty]

I reinstalled my build system, and during the grovel step I am once again getting the no-pie error as described in issue #5.

; cc -o /root/.cache/common-lisp/sbcl-1.4.11-linux-arm/root/quicklisp/dists/quicklisp/software/cl-libusb-20200218-git/libusb-grovel__grovel-tmpNSMC798T -g -no-pie /root/.cache/common-lisp/sbcl-1.4.11-linux-arm/root/quicklisp/dists/quicklisp/software/cl-libusb-20200218-git/libusb-grovel__grovel.o

After an hour of arduous debugging, I found the culprit.

On certain lisps, CFFI uses cc in places that it might otherwise use ld, but it applies the same flags, despite the fact that some versions of cc will refuse to accept them.

These flags are pulled dynamically from "/usr/local/lib/sbcl/sbcl.mk".

The bottom line is: SBCL and/or CFFI has a bug that is preventing your library from loading. And there's not a huge lot you can do about it.

Personally, I will be editing sbcl.mk and removing the offending keywords system-wide.

FYI, the problem is in c-toolchain.lisp, in the sbcl-toolchain-parameters function.

• It sets cc to be used in place of ld.
• It pulls the ld flags (which include -no-pie) from sbcl.mk and applies them blindly to cc, which is ill-prepared to receive -no-pie.

I have commented on the CFFI issue, although I doubt it will be given any credence.
