Describe the bug
Running make cgi inside src/newton fails due to the following error:

make: *** No rule to make target 'newton-irPass-estimatorSynthesisBackend/o', needed by 'cgi'.  Stop.

To Reproduce
Steps to reproduce the behavior:

1. Clone repo using git clone --recursive [email protected]:phillipstanleymarbell/Noisy-lang-compiler.git

CONFIGPATH=<path-to-repo>/home/janith/Noisy-lang-compiler/submodules/libflex
OSTYPE=linux
MACHTYPE=x86_64

3. run make in submodules/libflex.
4. run make cgi in src/newton.

Line 168 seems to be a duplicate of Line 163.

So removing this line fixed the issue. I'll make a PR with this change.
