+Subject: [PATCH] build-sys: check for lz4 in the old and new numbering scheme
+ (#4717)
+
+lz4 upstream decided to switch to an incompatible numbering scheme
+(1.7.3 follows 131, to match the so version).
+PKG_CHECK_MODULES does not allow two version matches for the same package,
+so e.g. lz4 < 10 || lz4 >= 125 cannot be used. Check twice, once for
+"new" numbers (anything below 10 is assume to be new), once for the "old"
+numbers (anything above >= 125). This assumes that the "new" versioning
+will not get to 10 to quickly. I think that's a safe assumption, lz4 is a
+mature project.
+
+Fixed #4690.
