[ft-devel] Testing PIC mode code (Re: Fixes for some compile and link errors when using FT_CONFIG_OPTION_PIC)

[suzuki toshiya]

During the overhaul for PIC build, I found that cache subsystem
of FreeType2 is not ready for PIC build, thus the demo programs
doing rasterization (e.g. ftview, ftbench) cannot be built.
Thus I can check if the code is compilable, but cannot check
if the code is working. Maybe most expected direction is the
porting of the cache subsystem for PIC build (even if there is
no real user of it on embedded system), but extending some demo
programs for FreeType2 without cache subsystem would be easier
first step.

# I assume FreeType2 built in PIC mode will work in the operating
# system that PIC mode is NOT required (e.g. Linux). If it's
# misunderstanding, please let me know.

Any comments?
