prefix/winnt/profile.bashrc: ensure libNAME.lib, libNAME.a

Libtool for winnt does create libNAME.lib as the static library, but
some build tools may expect libNAME.a.
Non-libtool build tools may also create a static library NAME.lib, which
needs to be duplicated to both libNAME.lib and libNAME.a, but not to
libNAME.so just because it does match the shared library naming scheme.
Also, do not provide symlinks but real files only, for some build tools
may source the MSVC environment and use the native toolchain.
