With kernel 5.0.6 we start seeing compile errors such as:
HOSTCXX -fPIC scripts/gcc-plugins/randomize_layout_plugin.o
In file included from <stdin>:1:
/usr/include/libelf/libelf.h:28:5: error: "__LIBELF_INTERNAL__" is not defined, evaluates to 0 [-Werror=undef]
#if __LIBELF_INTERNAL__
^~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
elutils-dev installs a different version of libelf.
