glibc/gcc/libgcc-initial: Delete do_build tasks for -initial
We've had a lot of users running into RSS issues where -initial recipes
were being installed into sysroots alongside their counterparts and
causing overlapping files issues.
In general this was through do_build dependencies. Such dependencies are
bad in general and I'd encourage people to compare the taskgraphs with
using a more specific dependency like do_populate_sysroot, do_image_complete
or do_deploy as often the more specific dependency will result in a much
cleaner build.
Regardless, we don't want -initial dependencies getting in the way like
this and there are cases a do_build dependency could make sense.
Deleting the do_build task in these cases makes sense since this is not
a build "endpoint" we'd ever want a user to use, its a behind the scenes
piece of bootstrappping.
Unfortunately to make this work, we need a newer bitbake version which
has a bitbake bug fixed.
