[oe] trouble building gcc-cross-initial first time

OK, i think there is something strange going on here.
In gcc-cross-initial.inc: PROVIDES = "virtual/${TARGET_PREFIX}gcc-initial"
In glibc.inc: PROVIDES = "virtual/${TARGET_PREFIX}libc-for-gcc"
In glibc-initial.inc: DEPENDS = "virtual/${TARGET_PREFIX}gcc-initial"
In gcc-cross.inc: DEPENDS = "virtual/${TARGET_PREFIX}libc-for-gcc"

I'd say that there is a circular dependency here.
Could this explain why the problem occurs in a multi-threaded build
environment and not in a single threaded one?
What's the way to solve this? Is there some way in bitbake to synchronize this?
