Hi Maintainer

When building inventor 2.1.5-10-17 on Ubuntu Saucy's builders, the build 
was successful on amd64 and armhf, but failed with the following error 
on i386 and powerpc.

/usr/bin/g++   -L/build/buildd/inventor-2.1.5-10/debian/tmp/usr/lib 
-shared -Wl,--whole-archive -Wl,-z,defs    -L/usr/X11R6/lib 
Decal.o          -lGL -lInventor -lInventorXt -Wl,--no-whole-archive -o 
Decal.so
/usr/lib/i386-linux-gnu/libc_nonshared.a(stack_chk_fail_local.oS): In 
function `__stack_chk_fail_local':
(.text+0x10): undefined reference to `__stack_chk_fail'
collect2: error: ld returned 1 exit status
make[4]: *** [Decal.so] Error 1

I found similar bug reports [1,2] and my understanding is that Decal.so 
is being linked against the static libc instead of the shared libc.

The attached patch explicitly links libc by appending -lc to Decal.c++'s 
LLDLIBS.

Regards
Graham
