Log Message

Add support for out-of-source builds.

* GNUmakefile (srcdir): Define it; default is "."
(vpath) [%.l, %.y]: Locate them, by reference to $srcdir
(vpath) [%.c, %.cpp, %.h]: Locate them in $srcdir, or $srcdir/libgroff
(CPPFLAGS): Incrementally add $srcdir and $srcdir/libgroff includes.
(CFLAGS, CXXFLAGS): Remove include path specifications.
