[64 bit] relocation truncated to fit: R_X86_64_PC32

trying to build octave I hit:

looking at gcc "3.17.16 Intel 386 and AMD x86-64 Options"

----------------------------------------------------------------
`-mcmodel=small'
     Generate code for the small code model: the program and its
     symbols must be linked in the lower 2 GB of the address space.
     Pointers are 64 bits.  Programs can be statically or dynamically
     linked.  This is the default code model.

`-mcmodel=kernel'
     Generate code for the kernel code model.  The kernel runs in the
     negative 2 GB of the address space.  This model has to be used for
     Linux kernel code.

`-mcmodel=medium'
     Generate code for the medium model: the program is linked in the
     lower 2 GB of the address space.  Small symbols are also placed
     there.  Symbols with sizes larger than `-mlarge-data-threshold'
     are put into large data or BSS sections and can be located above
     2GB.  Programs can be statically or dynamically linked.

`-mcmodel=large'
     Generate code for the large model.  This model makes no assumptions
     about addresses and sizes of sections.

---------------------------------------------------------------------
should I force the `-mcmodel=large' ?
