[PATCH 11/11] s390: Link vmlinux with '-z notext'

ld.bfd defaults to '-z notext' (although it is customizable with the
'--enable-textrel-check' configure option) but ld.lld defaults to '-z
text', which causes issues with building the kernel due to the presence
of dynamic relocations in sections that are not writable.

ld.lld: error: relocation R_390_64 cannot be used against local symbol; recompile with -fPIC

Add '-z notext' to avoid these errors, as this is expected, which
matches other architectures.
