litecross: Pass --enable-deterministic-archives to binutils, not gcc

When the gcc and binutils build trees were separated in defdbb4505,
--enable-deterministic-archives was accidentally left in FULL_GCC_CONFIG.
This had the effect of reverting commit e83fe4b8ce, breaking
reproducible builds (unless it was specified explicitly in config.mak).
