[CentOS] Problems compiling kernel module

Hi

I just upgraded a virtual Centos from 7.5 to 7.6 and now the VirtualBox
Extensions won't compile with the kernel.

I looked into the log file and found that I should try to execute:

make oldconfig && make prepare

but I get this result:
 scripts/kconfig/conf --oldconfig Kconfig
 #
 # configuration written to .config
 #
 scripts/kconfig/conf --silentoldconfig Kconfig
 make[1]: *** No rule to make target `arch/x86/syscalls/syscall_32.tbl',
 needed by
`arch/x86/syscalls/../include/generated/uapi/asm/unistd_32.h'.   Stop.
 make: *** [archheaders] Error 2


What could be wrong?
