Freetype2 does not compile with GNU Make 3.77

[Ram'on Garc'ia Fern'andez]

I have just tried to compile Freetype 2 beta 8 with GNU Make 3.77
and it did not work. It works fine with GNU Make 3.78. This is 
a Redhat Linux 6.2.

The problem is with the line
include $(wildcard $(SRC)/*/rules.mk) (freetype.mk: 192)

This kind of wildcard expansion does not appear to work with GNU Make 3.77

I think that requiring exactly the latest version of GNU Make is not a
good idea. It will place a barrier for the users wishing to compile
the Freetype library (or programs that need it).

A posible workaround is to replace that line by:

include $(shell echo $(SRC)/*/rules.mk)
