Found some old GNU Make patches of mine.

[Kaz Kylheku]

Hi all, 

It's as if I have just been hit by lightning. 

I found a large Subversion repository of code that I thought
had been lost for 13 years, from a startup that folded in 2010. 

It includes the changes I made to GNU Make 3.80 to make it
dump executable images after parsing the makefiles.
I'm sure I wrote about this before.

The time stamps are spaced close together because I was
likely converting a quilt patch stack into commits:

Change-ID: use-unexec 

Add --dump-image option to save an image and quit after loading the goal chain.
Some tricky things had to be done to make the restarting work, like
reallocating the argument vector into malloced memory, and disabling the use
of mmap for memory allocation.
