[Devel] Fix to freetype-config.in

[Matthew Crosby]

Hi!  I just installed freetype 2.0.1 under Solaris (2.5.1).  A couple
of minor niggles with the install, figured you've probably fixed them
already but thought I'd report them anyway.
First off, the make install failes because 
freetype-2.0.1/builds/unix/install-sh is not executable in the tar file,
should be easy to fix.
Second, the shipped version freetype-config.in has problems with seperate
--prefix and --exec-prefix.  Because it always sets exec_prefix_set to no,
it ignores the default --exec-prefix as put there by configure.  The
below install-sh fixes that issue, but also allows different ordering
of --exec-prefix and --prefix (which is where the gtk-config and so forth
fall down).
Third, Solaris will probably want a address@hidden@ as well as address@hidden@
under echo_libs.  No patch yet....
