You can keep your Buildroot tree unchanged and still have Buildroot
packages for your own application:
buildroot/
mysystem/
mysystem.mk
packages/
myapp/myapp.mk
myotherapp/myotherapp.mk
And then you can do something like this in mysystem.mk:
BR2_PACKAGE_MYAPP=y
BR2_PACKAGE_MYOTHERAPP=y
include packages/*/*.mk
And your Buildroot configuration, set BR2_PACKAGE_OVERRIDE_FILE to
"$(TOPDIR)/../system.mk".

Why would you want to do that absolutely? If your packages have
dependencies, put them in <yourpackage>_DEPENDENCIES, and your package
will be built after its required dependencies. There is no reason to
build after *all* packages.
