[Openmcl-devel] problems building interface databases on Debian multiarch

Hi,

I hit a bit of a snag with building the interface databases on Debian
unstable. Debian has switched to using multiarch, which puts headers
in different places than the traditional ones. Eg. <gnu/stubs.h> is
now in

/usr/include/i386-linux-gnu/gnu/stubs.h

instead of

/usr/include/gnu/stubs.h

The error log is given below.

At first I thought this would be a major problem, but then I realised
that one can probably just add the extra include paths to those that
ffigen searches, e.g. add the necessary include paths to

CFLAGS="-isystem ${FFIGEN_DIR}/include -isystem /usr/include -isystem  /usr/local/include -quiet -fffigen ${CFLAGS}"

in ffigen4/bin/h-to-ffi.sh. It seems that -isystem is the flag to use 
here.

Does this sound correct?  I'll try it anyway. but a confirmation would
be appreciated.

                                                        Regards, Faheem
