At least on platforms that use unixccompiler.py, the contents of the
extra_compile_args list ends up being passed to os.execvp().  An empty
string therefore ends up looking like the shell invocation 'gcc --foo --bar
--baz ""', and the zero-length string argument must mess things up.

Protection against this might be added by dropping all empty strings
from the list, but I don't think that's a good idea; if this was done,
how would you supply an empty string when you really want to?
