three remarks:
1) COND_ARCH_FPU_SUFFIX is _completely_ useless, to say the least.
2) TOPDIR_PREFIX and TOPDIR_SUFFIX don't hurt and are convenient for some corner-cases. I'd keep them.
3) I'd much prefer if we could rather settle on
TOOL_BUILD_DIR=$(BASE_DIR)/$(TOPDIR_PREFIX)$(ARCH)$(ARCH_FPU_SUFFIX)$(ARCH_MMU_SUFFIX)$(TOPDIR_SUFFIX)_toolchain
BUILD_DIR     =$(BASE_DIR)/$(TOPDIR_PREFIX)$(ARCH)$(ARCH_FPU_SUFFIX)$(ARCH_MMU_SUFFIX)$(TOPDIR_SUFFIX)_build

so you can conveniently rm -rf powerpc_nofpu_* (for example)
