Help/Support make: cc: Command not found

[ForTheTweaks 31 iPhone Xs 13.2.3]

Every time I try to run `make`, I get the following:

```

cc -I. -O3 -march=native -flto     -o filename filename.c

make: cc: Command not found

make: cc: Command not found

```

I've tried to make multiple different projects, this happens every time.

I have LLVM+Clang installed from BigBoss, theos installed by following @DADi's guide, and have searched online for a solution to this, without finding one.

When I try to run `clang make -v` instead of just `make`, I get this:

```

clang version 5.0.1 (tags/RELEASE_501/final)

Target: arm64-apple-darwin16.7.0

Thread model: posix

InstalledDir: /usr/bin

 "/usr/bin/ld" -demangle -lto_library /usr/share/llvm/lib/libLTO.dylib -dynamic -arch arm64 -iphoneos_version_min 5.0.0 -o a.out make -lSystem

ld: library not found for -lSystem

clang-5.0: error: linker command failed with exit code 1 (use -v to see invocation)

```

Does anyone know a solution to this? Do I have to build and install llvm and clang from it's source code?
