[PATCH] pseudo: fix link with new sqlite3

[Ross Burton <ross.burton@intel.com>]

If sqlite3 is built with FTS5 it uses log() from libm, but that linkage is lost
if we manually statically link so explicitly link to libm.

+If sqlite3 is built with FTS5 enabled then it links to libm.so for log(), but if
+we statically link to libsqlite3.a then this linkage is lost.
+
+Work around this by always linking to libm.so.
