I found the solution for this one.
The defaults are specified in the
poky/meta/conf/distro/include/tcmode-default.inc file.
What was happening is that when I set a couple of virual providers explicitly,
I always ended up missing a couple, and it was taking the gcc-4.7.1 related
recipes, because the over-rides weren't complete. the tcmode-default.inc file
has the full list of virtual providers for the toolchain, and the best way to
set up for an older version of the gcc compiler is to specify just a few
variables in the local.conf file as follows:
# Set the gcc toolchain version.
# Use wildcards %, to match the actual versions.
GCCVERSION = "4.5%"
SDKGCCVERSION = "${GCCVERSION}"
BINUVERSION = "2.22"
EGLIBCVERSION = "2.16"
UCLIBCVERSION = "0.9.33"
LINUXLIBCVERSION = "3.3.3"
