gcc/ch/Makefile.in: remove unnecessary invocations of gawk, sed

ch/Makefile.in unnecessary invokes gawk and sed when generating
hash.h. as you can see, the use of 'tr' in the first cmd (pipeline) in
the rule to hash.h insures that the result of the pipeline is all
upper-case, so there's no point in using the gawk and sed to convert
the first word in the line to upper case. (it's also worth noting
that even if it were worthwhile, that wouldn't work as-ins, because
it'd be looking for 'foo,,' rather than 'foo,'...)
I've tested a patch very similar to this one (identical other than
mucking with uses of srcdir), but i've not tested this _exact_ patch.
somebody should probably throw it into a build before they check it
in...
As previously noted, I don't have an assignment currently on file, but
this is another truly trivial one...
