Remove the old (unused) <supports_shared> config block. It specified

which architectures the OS supported shared libs on; in all cases it
was either all or none. Replace with new config build_shared [yes|no],
which defaults to yes but is set to no for MinGW and Cygwin since
shared libs don't seem to be working well there.
