[issue18125] Out-of-tree build cannot regenerate Makefile.pre

[Paul TBBle Hampson]

New submission from Paul TBBle Hampson:

Noticed in Python 2.7 but a quick look in the repository suggests this is also 
true in Python 3 releases.

The Makefile rule for Makefile.pre in Makefile.pre.in is:
# Build the toplevel Makefile
Makefile.pre: Makefile.pre.in config.status
CONFIG_FILES=Makefile.pre CONFIG_HEADERS= $(SHELL) config.status
$(MAKE) -f Makefile.pre Makefile

However, when built out-of-tree, Makefile.pre is in the build directory, as as 
config.status, but Makefile.pre.in is in the source directory.

So the rule should be
# Build the toplevel Makefile
Makefile.pre: $(srcdir)/Makefile.pre.in config.status
CONFIG_FILES=Makefile.pre CONFIG_HEADERS= $(SHELL) config.status
$(MAKE) -f Makefile.pre Makefile

Note that the recipe doesn't change, as config.status internally knows where 
Makefile.pre.in is found, so it's just the rule dependency that's wrong.

This bug results in No rule to create Makefile.pre.in if Makefile.pre is 
somehow newer than Makefile or Modules/config.c in the build tree.

Paul TBBle Hampson added the comment:

Forgot to mention, this is the only occurrence of a *.in file in 
Makefile.pre.in that isn't prefixed with $(srcdir)/
