build-aux/compute-symver-floor: Fix handling of spaces in CFLAGS #126

Closed rpurdie closed 3 years ago

rpurdie commented 3 years ago

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.
