+Subject: [PATCH e2fsprogs] build: Add SYSLIBS to e4crypt linking
+
+The $(SYSLIBS) was missing when linking the e4crypt application. This is
+available in the e4crypt.profiled variant, so I assume this was just
+missing in the normal variant and is not left out intentionally.
+
+This fixes building e2fsprogrs with -fsanitize=undefined in the global
+CFLAGS nad LDFLAGS.
