There aren't actually good tools to do it, although you could probably script
something with objcopy. In general, shared libraries are built as Position
Independent Executable (PIE) code, meaning accesses to their global symbols
bounce off a lookup table so that the dynamic linker dirties fewer
copy-on-write pages patching in symbols and you get more shared pages between
instances of programs using the shared library. Static libraries generally
aren't built that way (which produces smaller-per-instance but less easily
shared between instances code).
That's why they generally don't bother to make conversion tools fromone format
to the other, anyway. Rebuilding from source with the right flags produces
more efficient output.
If this is about libstdc++.a not existing in the current FWL, it's just
becuase I forgot to add a libstdc++.a->libuClibc++.a symlink in /tools/lib.
