all: add export linknames for assembly symbols accessed from other package
For Go symbols accessed from other package via linkname or
assembly, we have an export linkname from the definition side. We
currently don't always have the linkname directive for assembly
functions, for which external accesses are allowed. We may want
to tighten up the restriction. So add export linknames for the ones
that are needed.
