-- Update to 1.99.13:
-  * Drop fuzz-lzo-* patches, as they have been merged upstream.
-  * Allow overriding strip binary (not used in this build).
-  * Make -fanalyzer more happy: abort() and assert()ions to ensure
-    we always react to failed memory allocations.
-  * ddr_hash: Support reading/writing checksums from stdin/out "-".
-  * Fix aliasing issue with XORN function (in aes.h), spotted by
-    gcc-13: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108695
-    Drop workaround from Martin Liška again. 
-  * Higher optimization level for aes.c driver is beneficial for
-    key setup speed.
