[bug #13480] GD libraries not found on FreeBSD

Follow-up Comment #16, bug #13480 (project mldonkey):

Might another check in configure.in be the source? If you look at:
---
# testing for gd support
LIBPNG=no
AC_CHECK_LIB(png, png_create_read_struct , [LIBPNG=yes])

LIBJPEG=no
AC_CHECK_LIB(jpeg, jpeg_CreateCompress, [LIBJPEG=yes])

LIBGD_GIF=no
AC_CHECK_LIB(gd, gdImageGif,[LIBGD_GIF=yes])

LIBGD_PNG=no
AC_CHECK_LIB(gd, gdImagePng, [LIBGD_PNG=yes])

LIBGD_JPG=no
AC_CHECK_LIB(gd, gdImageJpeg, [LIBGD_JPG=yes])
---
The first check for PNG check PNG read ability it seems
(png_create_read_struct), and it sets the variable LIBPNG. Is that variable
actually used anywhere? And if it is, without the GD PNG libraries, PNG
reading will still succeed. So it probably will try to read a file it cannot
write. Hence an error...
So LIBPNG can only be true when LIBGD_PNG is true, and LIBJPEG can only be
true when LIBGD_JPG is true.
