So this is when compiling sim. Did you intend to compile gdb and sim,
or just binutils? If you really only wanting binutils (plus gas, ld,
gprof) then configure with --disable-gdb --disable-gdbserver
--disable-gdbsupport --disable-libdecnumber --disable-readline
--disable-sim. Bug reports about gdb and sim should be reported via
http://www.gnu.org/software/gdb/bugs/ or to bug-...@gnu.org
