[patch] toplevel configure.in: topsrcdir->srcdir

[Nathanael Nerode <neroden@doctormoo.dyndns.org>]

This replaces references to ${topsrcdir} with ${srcdir}.  This is correct,
since topsrcdir == srcdir when this is run; it is useful for autoconfiscation, 
because topsrcdir doesn't automatically exist in autoconf scripts, while
srcdir does.

Tested on i686-pc-linux-gnu.
