clisp currently fails on both kfreebsd-i386 and kfreebsd-amd64

Even clisp 2.38-7 (available from gnuab) is not buildable on 
current kfreebsd-i386 (neither with current libsigsegv 2.4-4, 
neither with libsigsegv 2.3-3). 
This is long standing indirect regression, cause still unknown :-(


There is also issue with libsigsegv in our glibc (fixed in r2025).
The pthread wrapper around signal handler does not pass 4th argument.   
As a result, loading of libpthread.so breaks functionality of libsigsegv


libsigsegv 2.4-4 needs small fixup for amd64,
upcoming libsigsegv 2.5 also for configure.ac/configure:

ffcall does not work correctly, see #451356

also main clisp needs fix up for kfreebsd-amd64:
