To reproduce the problem:
cd examples/matrixmultiply
make sw
touch matrixmultiply.c
make sw

The output of the second "make sw" is:
mkdir -p output
mkdir -p output/ip
cp ../../boards/CycloneV/DE1-SoC/ARM_Simple_Hybrid_System/legup_system.qsys
output/legup_system.qsys
# produces pre-link time optimization binary bitcode per source file
clang-3.5 matrixmultiply.c -emit-llvm -c -fno-builtin -I ../lib/include/ -m32
-I /usr/include/i386-linux-gnu -O3 -I ../../legup-library/ -fno-vectorize
-fno-slp-vectorize -o matrixmultiply.fe.bc -I ../../tiger/tool_source/lib
# linking may produce llvm mem-family intrinsics
../../llvm/Debug+Asserts/bin/llvm-link  matrixmultiply.fe.bc -o
output/matrixmultiply.bc
cp output/matrixmultiply.bc output/matrixmultiply.sw.parted.bc

Need to add another dependency check.
