[PATCH] dtc: supply a definition for YYRHSLOC if there isn't one

[Paul Gortmaker]

It seems that some machines, like a default RHEL4 install, will
not have a definition for YYRHSLOC, and that prevents building
dtc.  This supplies what appears to be the standard definition
for it in the event that the host system does not have it defined.
