pseudo: fix link of sqlite3 using pkg-config

pseudo: fix link of sqlite3 using pkg-config

If sqlite3 is built with FTS5 it uses log() from libm, it sqlite3 is built
with READLINE it uses tgetent from a curses lib and readline from libreadline,
if it is built using deflate from libz ... , but all that linkage is lost
if we manually statically link so explicitely extract extra static linking
options from pkg-config and force them into pseudo as well.

This commit obsoletes (so include the implicit revert)
