kbuild, modpost: fix unexpected non-allocatable section when cross compiling
The missing TO_NATIVE(sechdrs[i].sh_flags) was causing many
unexpected non-allocatable section warnings when cross-compiling
for an architecture with a different endianness.
Fix endianness of all the fields in the ELF header and
section headers, not just some of them so we are not
hit by this anohter time.
