-Subject: [PATCH] fix libtomcrypt/libtommath ordering
-
-To prevent build failures when using system libtom libraries and
-linking with --as-needed, LIBTOM_LIBS should be in the order
--ltomcrypt -ltommath, not the other way around, ie libs should be
-prepended to LIBTOM_LIBS as they are found, not appended.
-
-Note that LIBTOM_LIBS is not used when linking with the bundled
-libtom libs.
