Updated patch

Here's an updated patch which for me allows the built compiler to generate
binaries if I pass -sysroot and -isystem. The OSREL has to be in the --target
due to this change:

https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config.gcc?r1=222192&r2=222191&pathrev=222192

that was introduced due to this bug report:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65535

When the --target and --host don't match, gcc's configure decides you're
building a cross compiler, which we aren't doing here. So unfortunately it
seems like the right thing to do is make --target and --host match and to have
the OSREL in both for both gcc and binutils.

This change does that and after updating and rebuilding everything I seem to
have a working compiler.

Please test and see if this fixes the issues reported in this bug and the other
bugs mentioned.
