Hello-
I often find it convenient to run a new c-c++-common test from the
main build dir like:
$ make -j 2 RUNTESTFLAGS=dg.exp=new-test.c check-gcc-{c,c++}
I noticed that sometimes this produces a corrupted site.exp and then no
tests work until it is remade manually. To avoid the issue, it is necessary
to do "cd gcc; make site.exp" before running a parallel make from the top
level directory. The below patch fixes it by just making that dependency on
site.exp explicit in the top level Makefile. Is it OK please? Thanks...

A command like "make -j 2 check-gcc-c check-gcc-c++" run in the top level of
a fresh build directory does not work reliably. That will spawn two
independent make processes inside the "gcc" directory, and each of those
will attempt to create site.exp if it doesn't exist and will interfere with
each other, producing often a corrupted or empty site.exp. Resolve that by
making these targets depend on a new phony target which makes sure site.exp
is created first before starting the recursive makes.
ChangeLog:
* Makefile.in: Regenerate.
* Makefile.tpl: Add dependency on site.exp to check-gcc-* targets
