[HarfBuzz] mingw compilation problem with 811eefe

[Werner LEMBERG]

After doing a simple ./autogen.sh; make, with only

  checking for FREETYPE... yes

and all other packages (GLIB, GTHREAD, etc.) returning `no', I get the
following errors while creating libharfbuzz.dll.a:

  hb-ot-shape.cc:603: undefined reference to `__chkstk_ms'
  harfbuzz-indic.cpp:1199: undefined reference to `__chkstk_ms'

This is minGW; gcc version 4.5.2.
