Lewis Hyatt 56ca59a031 Makefile.tpl: Avoid race condition in generating site.exp from the top level
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

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
