Well, this check is wrong because if you need to use -liberty, than you have a non-shared
and thus unusable libbfd.

I'm now using

=====
old_LIBS=$LIBS
LIBS="-lbfd"
AC_MSG_CHECKING(whether we have a shared libbfd.so)
AC_TRY_LINK_FUNC(_sch_istable,,[AC_MSG_ERROR([
*** You libbfd is unusable for the debugger.
 *** Please read the binutils and libbfd issues section in README.FreeBSD.])])
LIBS=$old_LIBS
AC_MSG_RESULT(ok)
=====

and the README.FreeBSD file explains the issue.
