glibc-initial is needed to build gcc-cross-initial, which is needed to
build glibc-intermediate, which is needed to build gcc-cross, which is
needed to build glibc. Look at the package recipes, including
glibc.inc to see what's going on.
The seemingly different build order you noticed is probably due to
bitbake's fine-grained task dependencies. Maybe glibc was unpacked
before gcc-cross, but it most certainly wasn't compiled before
gcc-cross was staged.
