can't build shared libraries on sparc64-netbsd

Current trunk code fails to build shared libraries on sparc64-netbsd
because the generated relocations with -fpic don't have the range
necessary.  In general, any platform with sparc support that we want
to build for should use -fPIC instead of -fpic, with gcc.  (I haven't
checked whether openbsd or freebsd support sparc these days; I think
they're the only ones in our shlib.conf that we might care about.)

* shlib.conf (*-*-netbsd*): Use -fPIC instead of -fpic, which won't work on
sparc64 at least.
