Martin Storsjö f951837ce5 configure: Don't add -fPIC to cflags for target_os=win32
We skipped adding it to cflags for mingw/cygwin configurations
where the compiler either complains loudly or even errors out;
do the same for target_os=win32, for the case when building with
clang in msvc mode.

This wasn't needed for the actual msvc before, since msvc uses
msvc_common_flags to filter out this flag from cflags.
When building with clang in msvc mode, no such filter is used.

This fixes building shared libraries with clang in msvc mode.
