+Implement the SOURCE_DATE_EPOCH specification[1] for reproducible
+builds. If SOURCE_DATE_EPOCH is set, use it as timestamp instead of the
+current time.

+Subject: [PATCH] config: switch to AC_CHECK_LIB
+
+This fixes spurious build-errors on OpenWrt, where the AM_ICONV macro
+is undefined while invoking autoconfig. Later in the build, the ICONV
+LDOPTIONS are set to @LIBICONV@, failing the build.
