MIPS: Kbuild: Do not allow building vmlinuz when !ZBOOT
When CONFIG_SYS_SUPPORTS_ZBOOT is not enabled, we will still try to
build the decompressor code in arch/mips/boot/compressed as a
dependency for producing the vmlinuz target and this will result in
the following build failure:
OBJCOPY arch/mips/boot/compressed/vmlinux.bin
arch/mips/boot/compressed/decompress.c: In function 'decompress_kernel':
arch/mips/boot/compressed/decompress.c:105:2: error: implicit
declaration of function 'decompress'
make[1]: *** [arch/mips/boot/compressed/decompress.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [vmlinuz] Error 2
This is a genuine build failure because we have no implementation for
the decompress() function body since no kernel compression method
defined in CONFIG_KERNEL_(GZIP,BZIP2...) has been enabled.
arch/mips/Makefile already guards the install target for the "vmlinuz"
binary with a proper ifdef CONFIG_SYS_SUPPORTS_ZBOOT, we now also do the
same if we attempt to do a "make vmlinuz" and show that
CONFIG_SYS_SUPPORTS_ZBOOT is not enabled.
[ralf@linux-mips.org: Cleanup the makefile rule as suggested by James
Hogan.]
