FYI, a possibly better way is:

( CC=/opt/tools/gcc/bin/gcc ; export CC ; CXX=/opt/tools/gcc/bin/c++ ; 
export CXX ; ..../configure )

This has the benefit(?) of hard-wiring CC and CXX into the Makefile and 
hence making the build immune to changes in your path.

BTW, for testing the magic is more weird:

  make check RUNTESTFLAGS='CC_FOR_TARGET=/../cc CXX_FOR_TARGET=/../c++'

I think they should default to CC/CXX, but I've no idea where/why that 
isn't happening :-/
