Summary:                    Minor issue in kernel-headers.mk when making
".unpacked" target
Description: 
If you update the kernel headers tarball and run make against an already
built buildroot, the header files will be re-extracted, but they will not
be put in exactly the right place if the name of the extracted directory
includes the kernel version numbers.

For example, linux-libc-headers-2.4.25.tar.bz2 will be extracted to
$(TOOLCHAIN_BUILD_DIR)/linux-libc-headers-2.4.25, and then the mv command
will move the newly extracted headers into the already existing
$(TOOLCHAIN_BUILD_DIR)/linux directory, instead of replacing that
directory as desired.

The fix is to first remove the $(TOOLCHAIN_BUILD_DIR)/linux directory and
then do the mv command.
