Bug#926180: scilab: FTBFS on all

Some more testing:

* When run normally, or in gdb with "handle SIGSEGV nostop pass", 6.0.1 
has the IllegalStateExceptions and undocumented macro warnings, 6.0.2 
does not; both finish.

* valgrind --smc-check=all crashes at about the same place as this bug 
(but with a segmentation fault instead of illegal instruction) in 6.0.1, 
*later* but with the same message in 6.0.2.  Applying the 
promising-looking commits (66eff04a50, 4fadeff2ea, ef32e66c83, 
62afc99d6c, eca8e3d5f5, 92739afffb, 3014d410b3, b3016a0611) as a patch 
to 6.0.1 does *not* change this.

* valgrind --smc-check=all 
--vex-iropt-register-updates=allregs-at-mem-access (which the valgrind 
documentation suggests may be needed for SIGSEGV-catching programs, 
which Java is) gets past where this bug would happen in 6.0.1, then 
starts using >6GB of memory, near-hanging the system.

* qemu-x86_64-static -cpu Opteron_G3 (to match x86-bm-01, but as 
previously noted, qemu does not properly reject unsupported 
instructions) has the opposite behaviour: it crashes earlier on 6.0.2, 
hangs later (after this bug would happen, using a full CPU core) on 6.0.1.

* qemu+gdb crashes early in both 6.0.1 and 6.0.2.

The main packaging difference between 6.0.1 and 6.0.2 appears to be 
removed patches; I haven't checked if the patches in question are 
already included in 6.0.2.
