[PATCH 19.07 5/6] toolchain: kernel-headers: fix check target for kernel Git tree

[Petr Štetiar]

Currently the check target fails if the kernel Git tree is used:

 $ make toolchain/kernel-headers/{download,check}

  make[2]: Entering directory 'toolchain/kernel-headers'
  Makefile:105: *** ERROR: Unknown pack format for file openwrt/tmp/dl/.  Stop.
  make[2]: Leaving directory 'toolchain/kernel-headers'
  toolchain/Makefile:100: recipe for target 'toolchain/kernel-headers/check' failed
