[patch] Remove process IDs from temprorary file names

[Nathanael Nerode]

This has been causing all kinds of trouble with my attempted top level
bootstrap.  Is this OK for mainline?  Although not technically a bugfix,
it avoids some Future Evil.

What do people think about this?  And why was it being done anyway?....

	* Makefile.in: Change temporary intermediate file names to avoid
	using process IDs, so as to get reproducible debug information.
