Subject: [PATCH 1/2] boost: upgrade to 1_89_0

libs/system/src/error_code.cpp no longer exists in boost so the static
boost_system library can be removed

<https://dev-www.libreoffice.org/src/boost_1_89_0.tar.xz> has been generated (on
Debian 12) with

-# SYNOPSIS
-#
-#   AX_BOOST_SYSTEM
-#
-# DESCRIPTION
-#
-#   Test for System library from the Boost C++ libraries. The macro requires
-#   a preceding call to AX_BOOST_BASE. Further documentation is available at
-#   <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_SYSTEM_LIB)
-#
-#   And sets:
-#
-#     HAVE_BOOST_SYSTEM
