s390: Fix linker error when -no-pie option is unavailable

The kernel build may fail if the linker does not support -no-pie option,
as it always included in LDFLAGS_vmlinux.

Error log:
s390-linux-ld: unable to disambiguate: -no-pie (did you mean --no-pie ?)

Although the GNU linker defaults to -no-pie, the ability to explicitly
specify this option was introduced in binutils 2.36.

Hence, fix it by adding -no-pie to LDFLAGS_vmlinux only when it is
available.
