Makefile needs to compile with -fPIC option to install

[ndrein]

Hi,

I've tried install R-snappy, but I get errors when trying to "make":

Full output below:

[nreinhardt@qlogin6 R-snappy2]$ make
R CMD COMPILE r-snappy.c

I modified R-snappy/Makefile to compile with -fPIC, and the installation works. I've tested the sample usage given, and that works as well.
