[sr #110537] AC_SEARCH_LIBS does not honor --with-sysroot=

Follow-up Comment #4, sr#110537 (group autoconf):

Autoconf doesn't have generic support for --with-sysroot.  Like all --with and
--enable options, if you pass it to a configure script that doesn't define
what it does using AC_ARG_WITH, it's just ignored.

In order to add a generic --with-sysroot option, we would first need to work
out a detailed spec for what it should do, and a plan for how to add it
without stepping on the toes of configure scripts that *do* already have an
AC_ARG_WITH([sysroot], ...).  Someone other than me needs to lead that design
discussion; I don't have the time nor do I have any relevant experience.

This is definitely not going to happen for 2.72.
