-Fix revision number
-
-In 0002-shared-libs-for-lua.patch, revision number is used to set 
-library name:
-TO_SOLIB = liblua.so.$(R)
-
-However, library is built using PKG_VERSION which is passed only during
-build step:
-$(CC) -o $@.$(PKG_VERSION) -shared -Wl,-soname="$@.$(PKG_VERSION)" $?
-
-As a result, dynamic library is not installed in staging or target paths
-since bump to lua 5.3.5
-
-So, instead of replacing R by PKG_VERSION and passing this variable in
-all steps, simply update R to 5
