setenv ARCH sparc
make mrproper
make allmodconfig
make init/main.o

scripts/mod/empty.c:1: error: -m64 is not supported by this configuration
scripts/mod/empty.c:1: error: -mlong-double-64 not allowed with -m64
scripts/mod/empty.c:1: error: -mcmodel= is not supported on 32 bit systems

akpm:/usr/src/25> grep SPARC .config 
CONFIG_SPARC=y
# CONFIG_SPARC32 is not set
CONFIG_SPARC64=y
CONFIG_SPARC64_SMP=y
CONFIG_SPARC64_PAGE_SIZE_8KB=y
# CONFIG_SPARC64_PAGE_SIZE_64KB is not set
CONFIG_SPARC64_PCI=y
CONFIG_INPUT_SPARCSPKR=m
CONFIG_SND_SPARC=y
# Misc Linux/SPARC drivers

wtf?  How'd sparc64 get set?

Maybe I'm supposed to use ARCH=sparc32 now?  ARCH=sparc used to work.

akpm:/usr/src/25> setenv ARCH sparc32
akpm:/usr/src/25> make mrproper
Makefile:213: *** ARCH changed from "sparc" to "sparc32". Use "make mrproper" to fix it up.  Stop.

lol.

akpm:/usr/src/25> setenv ARCH i386
akpm:/usr/src/25> make mrproper
Makefile:213: *** ARCH changed from "sparc" to "i386". Use "make mrproper" to fix it up.  Stop.

help.
