It means that "-mcode-model=medlow" is not making it into the module build cflags somehow. This relocation can only occur for sparc64 code models other than "medlow".
I did a test Debian build using my Sun Fire V120 running to double check the build with the 2.6.27-1@experimental.1 sources. This fails in the same way that the official build fails.
Looking at the build output it seems to end up building setup_sparc but I think it should be building setup_sparc64 in the rules.

Looking through debian/rules it is using DEB_HOST_ARCH to determine which version of setup_ to run.
richm@shirehall:/usr/src/linux-2.6-2.6.37$ grep DEB_HOST_ARCH debian/rules
DEB_HOST_ARCH := $(shell dpkg-architecture -qDEB_HOST_ARCH)
$(MAKE) -f debian/rules.gen source_$(DEB_HOST_ARCH)
$(MAKE) -f debian/rules.gen setup_$(DEB_HOST_ARCH)
$(MAKE) -f debian/rules.gen build_$(DEB_HOST_ARCH)
$(MAKE) -f debian/rules.gen binary-arch_$(DEB_HOST_ARCH)
dpkg-architecture reports the settings as follows
richm@shirehall:/usr/src/linux-2.6-2.6.37$ dpkg-architecture
DEB_BUILD_ARCH=sparc
DEB_BUILD_ARCH_OS=linux
DEB_BUILD_ARCH_CPU=sparc
DEB_BUILD_ARCH_BITS=32
DEB_BUILD_ARCH_ENDIAN=big
DEB_BUILD_GNU_CPU=sparc
DEB_BUILD_GNU_SYSTEM=linux-gnu
DEB_BUILD_GNU_TYPE=sparc-linux-gnu
DEB_HOST_ARCH=sparc
DEB_HOST_ARCH_OS=linux
DEB_HOST_ARCH_CPU=sparc
DEB_HOST_ARCH_BITS=32
DEB_HOST_ARCH_ENDIAN=big
DEB_HOST_GNU_CPU=sparc
DEB_HOST_GNU_SYSTEM=linux-gnu
DEB_HOST_GNU_TYPE=sparc-linux-gnu
I will try a package build forcing DEB_HOST_ARCH to sparc64 and see if
that builds the right packages.
