The straightforward solution is to use a writable source directory.
Since you are not using the straightforward solution, you have to use
some other solution.

No. That would make everything more complicated. It would also make
the contents of the distribution tarball unpredictable: its contents
would depend on what software was installed on the computer that runs
"make dist", whereas it does not currently depend on that.
I am suggesting that we require the machine on which Open vSwitch is
built to have Python installed. Then we can always generate
ofp-errors.inc at build time, so there is no need to distribute it.
