Mention that --enable-lto is broken for MSVC
Mention that --enable-lto is broken for MSVC

I don't have the inspiration to fix it. I get unresolved symbols
"__declspec(dllimport) public: virtual class com::sun::star::uno::Any __cdecl
cppu::WeakImplHelper<class com::sun::star::container::XEnumeration>::
queryInterface(class com::sun::star::uno::Type const &)" etc when linking the
fwk library in framework.

Also, surely we require GCC to be >= 4.6 now, no need to mention that.
