+This is based on a patch taken from alpinelinux, however, duplicated
+libstemmer.o and stemwords targets were removed and the patch was
+rebased on top of v2.2.0 tag.
+
+Created shared library contains a lot of relocations, which slow down loading.
+It is known issue and probably the main reason why upstream does not support
+shared library yet [1].
