See bug #672454.

clozurecl compiles and works fine with the upstream-provided compilation 
flags. So, we cannot ask the upstream to solve our problems for us.

clozurecl compiles and works fine (for me this means that it can compile 
maxima and fricas, and they work) in the 13.0 profile. In the 17.0 one, 
its compilation loops forever on ~x86; on ~amd64 it compiles, but does not 
work properly (cannot compile maxima, bug #665364). So, the reason is in 
the new compilation or linking flags introduced in 17.0.

Is it possible to compile one specific package with compilation/linking 
flags closely following the 13.0 ones? How?

If after this fix it will be able to compile maxima and fricas, and they 
will work, that would be sufficient for me.

-fno-PIE, -fno-PIC are two potentially useful options.  Possibly more. 
Once you figure out which of them is necessary, you should tell upstream
to append it instead of relying on unsafe compiler defaults.

No.  After this fix it will be gone, and people will be able to compile
maxima and fricas using a working clisp compiler.

Oh, come on. The 17.0 profiles introduced rather daring compiler and
linker options, and clozurecl is not the only package broken by them.
Most of the Lisp packages (including Emacs) are affected, because their
dumping of the executable is incompatible with PIE. That doesn't make
them "bad quality packages". It simply means that the PIE flags hadn't
previously been encountered upstream, or not reported to them.

Still, you could report it upstream, maybe with a patch for their build
system?
