Subject: [PATCH] Makefile: run everything internally with float

- treat floating point constants as single precision
  (this removes all dependencies for double)
- use internal.ldf linker script
  (puts libc functions in local memory)

speedup is immense. running code from external memory
is extremely slow, especially when all cores fight for it.
