[binutils-gdb] sim: drop duplicate header checks


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=5cddc23a3a0b855858e8eca93d6dd90aec00d914

commit 5cddc23a3a0b855858e8eca93d6dd90aec00d914
Author: Mike Frysinger <vapier@gentoo.org>
Date:   Thu Feb 19 03:50:11 2015 -0500

    sim: drop duplicate header checks
    
    The SIM_AC_COMMON macro already checks for a bunch of headers, so specific
    sim ports need not do it themselves.
