          Severity: normal
          Priority: P3

Patch to generate header insn-opinit.h early

Bootstrap failure on parallel build of gcc cross compiler for ARM target.
Single job build unaffected and verified to work.
In my particular circumstance, the first pass builds successfully however the
second pass, which builds libgcc as well, fails due to above reason.

Build error:
In file included from <path_to_gcc_src>/gcc/lra-constraints.c:127:
<path_to_gcc_src>/gcc/optabs.h:24:25: error: insn-opinit.h: No such file or
directory

Reason: Prerequisite header file 'gcc/insn-opinit.h' not generated before being
required.

Solution: add 'insn-opinit.h' to 'generated_files' variable in
'gcc/Makefile.in' where prerequisite files are declared (obvious it should be
there) - see attached patch.
