another update necessary for clisp 2.49

[Manfred Gahr]

When trying to compile CLISP 2.49 on an up-to-date Kubuntu 10.10, I get the errors described in:
http://article.gmane.org/gmane.lisp.clisp.general/13435 and
http://article.gmane.org/gmane.lisp.clisp.general/13436

According to the links above, I tried to use the CVS head (2011-03-22) of libffcall for building, and that works.

the crash is cause by linking libffcall dynamically.
it should be linked statically.
see https://bugs.launchpad.net/bugs/987617
workaround:
in the clisp build directory:

perl -p -i -e "s,-lavcall,/usr/lib/libavcall.a,g" `grep -I -r -l -- -lavcall .`
perl -p -i -e "s,-lcallback,/usr/lib/libcallback.a,g" `grep -I -r -l -- -lcallback .`
make clean full check

Actually, the reporter is correct in the following sense:
upgrading libffcall to upstream cvs 2012-04-24 will solve the problem
because that version disables creation of shared libraries altogether.
