premake5 gmake --freesce retargets the one ps2 platform at freesce (its own ee-gcc 2.9 + newlib; FREESCE/FREESCE_GCC roots, defaulting to /usr/local/freesce) -- a premake-time choice since the 2.9 and 3.2 C++ ABIs don't link. The tools/freesce wrappers strip premake's gcc-3-style dep flags. demoreel_cd_freesce.elf now links with zero SCE inputs: freesce crt chain, newlib libc/libm, and ctorgen to register the PluginList ctors gcc 2.9 leaves orphaned.

# PS2 build, two flavors:

# this machine; see librwps2/Makefile for the pattern).
