Currently, the recipe which uses PACKAGES_DYNAMIC usually generates
a lot of packages which costs a lot of time on building the recipe
and do_rootfs, for example, the perl and kernel:

$ ls tmp/deploy/rpm/armv5te/perl-module-* | wc -l
621

$ ls tmp/deploy/rpm/qemux86/kernel-module-* | wc -l
268

Also, the eglibc-locale generates more than 300 packages.

Take perl as an example:

1) We generate 621 perl-module-* packages, but the package *perl-modules*
    requires all of them, so once *perl-modules* is installed, all the other
    perl-module-* will be installed and we can't remove any of them since
    perl-modules rdepends on it, if there is a way to package all of these
    perl-module-* into one package (they are about 10MB), it would save a lot
    of time on do_package* and do_rootfs.

2) The nativesdk.bbclass can't support PACKAGES_DYNAMIC, for example, it can't
    change the perl-module-app-cpan to nativesdk-perl-module-app-cpan since
    there is no perl-module-app-cpan in PACKAGES when nativesdk.bbclass
    changes the variable's name.

Can we add a way to let the PACKAGES_DYNAMIC be optional ? for example,

PACKAGES_DYNAMIC[perl] = "0"

will disable the perl's PACKAGES_DYNAMIC, and will pack the files as other
recipes do, and of course we need to do some work on the recipe.
