Complain if we can't find /lib/modules/uname -r/build/Makefile.

Tue Aug 30 16:57:33 2005  Søren Sandmann  <sandmann@redhat.com>

	* configure.ac: Complain if we can't find /lib/modules/`uname
	-r`/build/Makefile.

	* process.c (process_lookup_symbol): Take an address of 0x1 to
	mean "in kernel".

	* module/sysprof-module.c (timer_notify): When reporting in-kernel
	time, give the current pid instead of -1.

	* TODO: updates

Before 1.0:
* Fix cache so that it correctly reloads libraries when new ones are
installed. (Cache can go stale - probably just dump the cache when
a new profiling session is started). Though printing debug stuff
doesn't seem to produce anything unexpected.
* Build system
- Find out what distributions it actually works on
(ask for sucess/failure-stories in 0.9.x releases)
