there is already an option for this:
mv src/math src/.math
now you disabled math
if you don't like such hacks then you can add
SRCS:=$(filter-out src/complex/%,$(SRCS))
SRCS:=$(filter-out src/math/%,$(SRCS))
to your config.mak
i'm not sure how safe is this: libc uses some math
functions (at least stdio uses frexpl for printf)
