Fix static_sdk_tools by using static libicuuc

The static_sdk_tools build builds sqlite3 with BUILD_HOST_static=1,
which forces it to be linked as a static executable.  Switch the host
build to make libicuuc and its transitive dependencies static so that
the static binary can link without missing symbols errors.

Test: m static_sdk_tools TARGET_RELEASE=trunk dist BUILD_HOST_static=1
