Emacs 23.0.60 (CVS trunk): configure outputs wrong information about libotf and m17n-flt

[Ulrich Mueller]

In GNU Emacs 23.0.60.1 (i686-pc-linux-gnu, GTK+ Version 2.12.5)
 of 2008-02-02 on a1iulm2
Windowing system distributor `The X.Org Foundation', version 11.0.10300000

configure's report displays "no" for libotf and m17n-flt, although
configure was called with these options, and the corresponding
variables are set in src/config.h:

  Does Emacs use -lm17n-flt?                              no
  Does Emacs use -lotf?                                   no

But the generated src/config.h contains the lines:
#define HAVE_LIBOTF 1
#define HAVE_M17N_FLT 1


Here are the relevant pieces from the build log:
