kernel: add a workaround to rebuild vdso.so.dbg after genvdso

Currently the build fails with

  'arch/mips/vdso/vdso.so.dbg' already contains a '.MIPS.abiflags' section

if the file already exists from a prior build.

Add a makefile rule to force the rebuild of vdso.so.dbg if genvdso has
has been changed to workaround the failure.
