[Bug-apl] configure should not assume bash everywhere

[Marcin Cieslak]

There is a little incompatibility with Bourne shell in
the configure script. The whole thing should probably be changed,
but for now this is a quick fix:

Index: configure.ac

 echo "configure: creating $srcdir/src//buildtag.hh"
 rm -f $srcdir/src/buildtag.hh
-cd $srcdir/src ; source ./buildtag ; cd ..
+cd $srcdir/src ; . ./buildtag ; cd ..
 
 # create src/makefile.h
 #

Due to generation of files this way the out-of-tree is currently broken,
will provide a fix later.
