I'm curious.  What output from "make" do you see if you touch ldlex.l
and then run make?  ldlex.c ought to be regenerated via a .l.c rule,
even without --enable-maintainer-mode during configure.

I get the following.
make[4]: Entering directory '/home/alan/build/gas/all/ld'
/bin/bash /home/alan/src/binutils-gdb/ld/../ylwrap /home/alan/src/binutils-gdb/ld/ldlex.l lex.yy.c /home/alan/src/binutils-gdb/ld/ldlex.c -- flex
