           Summary: wine can't load freetype if the latter is built with

Proposed workaround

If freetype (tried freetype 2.7, wine 1.9.23; probably also valid for other
versions) is built with harfbuzz support, wine complains about:

Wine cannot find the FreeType font library.  To enable Wine to
use TrueType fonts please install a version of FreeType greater than
or equal to 2.0.5.

Adding some debug statements, it turns out that wine_dlopen fails not because
the library isn't there, but because dlopen barfs because it can't resolve
hb_ft_font_create in libfreetype.so.6. (Same for libfontconfig.so.1).

A fix (workaround?) is to use RTLD_LAZY instead of RTLD_NOW when dlopening
freetype and fontconfig -- seems to work well after that.

Patch relative to wine-staging 1.9.23 attached.
