That yields for 15:GA

   Mesa-drivers
   bcc
   beignet
   gnome-builder
   gnome-code-assistance
   libclc
   meson-testsuite
   rust

and for 15:SP1:GA

   Mesa-drivers
   bcc
   beignet
   gnome-builder
   gnome-code-assistance
   libclc
   meson-testsuite
   rust

and nothing in SP2/3 or the Update repos (seems project inheritance doesn't
work for whatdependson).  The above is for x86_64.  Since SP2 Mesa-drivers
depends on a versioned llvm version.  Oddly enough there's a bcc in SP3
as well and it depends on llvm but osc whatdependson doesn't list it.

Thus take this with a grain of salt.
