Erk, not really. It may be worth analysing the build's output carefully to
make sure there isn't something obvious being reported that wasn't treated
as a fatal error. Perhaps just try rebuilding again from an empty build

The generation of insn-flags.h is handled by the genflags program which is
part of the build. However it's meant to "just work". I just tried it now
for me for the i386-elf target and it worked for example. If this is the
same target you are using, try installing the attached insn-flags.h file in
the gcc subdirectory of your build tree.

Otherwise ask on the gcc@gcc.gnu.org list. You can find details at

Sorry I can't be more help.
