func_extract_archives removes gentop

[Peter O'Gorman]

Hi,

Currently libtool's func_extract_archives removes the dir, then recreates 
it. It is breaking my forward port of Alexandre Oliva's patch to rename 
objects before putting them in the archive if there are name conflicts.

Now, I could ensure that every time func_extract_archives is called it is 
given a unique directory, or I could 'fix' func_extract_archives to not 
remove the dir.

Any preference?

Peter
