conftest.c gcc: error: conftest.c: No such file or directory (no replies)

I enabled cryptodev hardware encryption on PogoPlug E02 using the latest Bodhi rootfs. I'm trying to compile an application but I'm getting the error using the following option

./configure CFLAGS="-march=native"

If I run the command manually I get

gcc -march=native conftest.c
gcc: error: conftest.c: No such file or directory
gcc: fatal error: no input files
