Subject: [PATCH] Fix build with LLD

LLVM's LLD handles the -retain-symbols-file option (used by
-export-symbols-regex in libtool) differently from GNU ld, causing
undefined references during link. This commit removes the
-export-symbols-regex option from libcalf_la_LDFLAGS since by default
libtool exports all symbols anyway, so it should not be necessary.
