Since commit 4c0f032d4963 ("s390/purgatory: Omit use of bin2c"),
s390 builds the purgatory without using bin2c.
Remove 'select BUILD_BIN2C' to avoid the unneeded build of bin2c.
Fixes: 4c0f032d4963 ("s390/purgatory: Omit use of bin2c")

The purgatory/ directory is entirely guarded in arch/s390/Kbuild.
CONFIG_ARCH_HAS_KEXEC_PURGATORY is bool type.
$(CONFIG_ARCH_HAS_KEXEC_PURGATORY) is always 'y' when Kbuild visits
this Makefile for building.

This is equivalent to the pattern rule in scripts/Makefile.build.
Having the dependency on $(obj)/purgatory.ro is enough.

Applied, thanks!
BTW, it looks like x86 and riscv also need similar change.
In addition, x86 use of CONFIG_ARCH_HAS_KEXEC_PURGATORY vs CONFIG_KEXEC_FILE
is not consistent with other architectures (may be even incorrect?).

A patch for x86 exists:
https://lore.kernel.org/all/20220616072407.2317131-1-masahiroy@kernel.org/
I will send riscv patches later.

I thought of this when I reworked Makefiles,
but did not touch this part.
