Fix windows build tools deps
commit 06c72097:
build-tools/yasm.recipe: Don't add -lintl to LDFLAGS
This might've been needed 6 years ago when it was added, but it is not
anymore, and in fact it causes a build failure if gettext-tools isn't
available.
commit cf86f311:
gettext-tools.recipe: Remove unnecessary dependencies on Windows
mingw-runtime is already implicitly added, automake is already in the
deps list.
