-fPIC for libnetdissect

[Michael Richardson <mcr () sandelman ca>]

When building libnetdissect into a virtual switch (uml_netjig), I started to
get:
   /usr/bin/ld: /home/mcr/stuff/x86_64/tcpdump-4.8.1/libnetdissect.a(print-ripng.o): relocation R_X86_64_32 against 
`.rodata' can not be used when making a shared object; recompile with -fPIC

which is odd, since I'm not trying to make a shared object, just a final link
of the executable.  But, adding -fPIC to the build works.

a) any reason we shouldn't build with -fPIC when using gcc?
b) any advince in a way that doesn't shoot non-gcc builds in the foot?
