buildworld failure r223619 to 225128

make buildworld failed trying to upgrade from r223619 to r225128.
(Note: Updating other boxes from r224774 to r225119 went flawless)

On failing laptop (Toshibs Sat C655D)

I do "rm -r /usr/obj/*" and make clean (in /usr/src)  before doing
buildworld on all boxes.
I also tried compiling new GENERIC kernel then doing buildworld.  It
failed with same message.

Reverted to old/original kernel and tried "make depend" in /usr/src.
It failed with... (by hand again)

===> lib/clang/libllvmarmasmparser (depend)
tblgen -l /usr/src/lib/clang/libllvmarmasmparser/../../../contrib/llvm/lib/Target/ARM

I tried my best to make sure there are no typos.

Any suggestions?

I thought of 3 options...
1) update to r224774 first, then to r225119 (or r225128).  To mimic other boxes.
2) build/install new kernel then "make depend" and then try buildworld.
3) find help from mailing list to fix this buildworld error.  ;-))

Number 1 .... might work.  Shot in the dark.
Number 2 ... I'm already past r221543, so "make depend" shouldn't be
required, and I'm not in that small version window that requires
installing new kernel before buildworld.
Number 3 .... email mailing list for help....tada!!!

Any help or suggestions will be appreciated.
Thanks,
