[distcc] Preprocessed output to make's stdout instead of to remote distccd

[Martin Pool]

Terry,

If you run your version of gcc with "gcc -E -MD foo.c", then do you
get dependencies in foo.d, and preprocessed output on stdout?

I realized on the weekend that distcc may be able to handle this case
reasonably by never using -o with -E, but instead just capturing
stdout to get the preprocessed source.  This might also improve
compatibility with other compilers that disagree with gcc on how this
combination of options should be handled.

Thanks,

Linux is the operating system of the people and pretty soon they may
even be able to use it.
