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)
