| If you pass CFLAGS with a leading space, " " gets passed to popen and convinces |
| gcc to try and open a file called " ". This results in a confusing error message |
| like: |
| |
| x86_64-pokysdk-linux-gcc: error: : No such file or directory |
| |
| Avoid this by stripping empty elements out of CFLAGS. |
