Well, with the nice Config.in.legacy stuff you've done, you've opened
new horizons to people like me who like to rename config options just
for the sake of it :-)

Yes, I believe so.

Yes, I agree. For now, the BR2_PREFER_STATIC_LIB=y configurations in
the autobuilders are raising a sufficient number of issues, so let's
try to solve those first. Once this settle down, I'll enable something
that checks whether any shared library is installed in the
BR2_PREFER_STATIC_LIB=y case, and which will make the build fail if
it's the case.

Best regards,

Thomas
