'On certain architectures (AMD64 amongst them), shared libraries *must*
be "PIC-enabled".'

That said, calling flags for the C++ compiler 'CFLAGS' is quite eh
'uncommon'. And frankly, people should stop hard-coding that stuff and
ask octave-config for it. That's what the script is for.

Bonus points for people compiling the above with a self-compiled C++
compiler under their $HOME.
