Bug#802517: Freecad bug

[Michael Zoran]

Hi, I solved the problem.  This appears to be an issue with gcc-5.  
When I recompile oce with gcc-4.9, all the regression tests of oce pass
and freecad seems to be working correctly.   If I compile oce with gcc-
5, some of the regression tests fail and freecad crashes.  
I noticed that the failing regression tests where removed from the -7
release of oce.

All I did was add these lines to the top of the rules file.

export CC := /usr/bin/gcc-4.9
export CXX := /usr/bin/g++-4.9
CFLAGS   := -g -O3
CXXFLAGS := -g -O3
LDFLAGS  := $(shell dpkg-buildflags --get LDFLAGS)

The CFLAGS and CXXFLAGS change is not important, and was just part of
trial and error.  I didn't have time to recompile and test without out.

The "export CC" and "export CXX" is the important part since it forces
the compile to use gcc-4.9.

I also changed the control file to add gcc-4.9 and g++-4.9 as "Build-
Depends".

I was able to recompile oce with the changes with pbuilder on amd64.  
I'm compiling armhf with pbuilder now, but I think it's going to take a
long time for the compile to finish.
