Try this minimal Buildroot config:
BR2_sparc=y
BR2_STATIC_LIBS=y
BR2_TOOLCHAIN_EXTERNAL=y
You will get a pre-built uClibc toolchain that will build a static
busybox binary. You should find it under output/target/bin/.
The config is based
support/config-fragments/autobuild/br-sparc-uclibc.config, with
BR2_STATIC_LIBS=y added.
Hope this helps,
baruch
