Very likely:

        * gcc-interface/targtyps.c: Do not include tm_p.h

        * gcc-interface/Make-lang.in: Update dependencies.

The same error occurs for java on ARM, see PR44335.  I posted a patch to fix
that one (must include both tm.h and tm_p.h in jcf-parse.c) that but so far has
gotten no response to it.

Fixing by reverting Steven patch is not enough to regain bootstrap on arm, here
is the error during stage2:

> Fixing by reverting Steven patch is not enough to regain bootstrap on arm, here
> is the error during stage2:

This is a new unrelated error caused by r160458.  You should IMO have opened a
new PR for it.  Anyway, the patch below should fix it.  Tested in a cross so
far, I'll do a native bootstrap of 4.6 head + this tomorrow.  The declaration
bug for 'vec' is obvious.  The fact that 'op1' is extracted but unused makes me
a bit nervous.

Reverting Steven patch with your fix is enough to get back bootstrap:
