ninja: De-dup libraries and use --start/end-group Now we aggressively de-dup the list of libraries used while linking, and when linking with GNU ld we have to enclose all static libraries with -Wl,--start-group and -Wl,--end-group to force the linker to resolve all symbols recursively. This is needed when static libraries have circular deps on each other (see included test). The --start/end-group change is also needed for circular dependencies between static libraries because we no longer recursively list out all library dependencies. The size of build.ninja for GStreamer is now down to 6.1M from 20M, and yields a net reduction in configuration time of 10% 8 years ago			`st1 = static_library('st1', 'lib1.c', 'prop1.c')`
