Is it possible to do a cross compile of gcc-4.7.2 on AMD x86_64 to
produce i686 target ?
My build, host and target parameters are amd64-pc-linux-gnu,
amd64-pc-linux-gnu and i686-pc-linux-gnu. My native compiler again is
a 64 bit compiler emitting default 64 bit object code.
Yes, it is possible.
It is also usually unnecessary. A typical x86_64 compiler
installation will produce 32-bit x86 code with the -m32 option.

That switches you over to a 32-bit compiler, taking advantage of the
support of 32-bit execution under this OS. In many current x86_64
installations, the 32-bit compiler is an additional option requiring the
primary gcc development system option.
