[Bf-committers] Solid Makefile

[Campbell Barton]

Just looking at ./extern/Makefile and solid is being built even if the 
game engine is not.

line 37 - DIRS = qhull/src solid

Could we make solid only get built if the GE is enabled? - like bullet 
currently is?

I tested and blender builds fine if solid is not built-

ifneq ($(NAN_NO_KETSJI), true)
    DIRS += bullet
    DIRS += solid # < added this line.
endif
