HEAD: pass environment to new test suite

[Ralf Wildenhues]

It's actually advantageous if `./testsuite' knows about the environment
variables we set for it: that way, issuing
  ./tests/testsuite.dir/09/run -x CFLAGS=-g

works as intended: overrides CFLAGS, but uses the same other variables.
So, let's have TESTSUITE_ENVIRONMENT as command line arguments, instead
of setting it beforehand.  And let's get rid of that ugly workaround in
LT_AT_TAG that we used before we passed all compilers anyway, so that CC
and CXX etc. can be overridden, too.

OTOH, there is an exception: we want to set $CONFIG_SHELL, because
that is what we start testsuite with.

Any reasons against this?

Cheers,
Ralf

        * Makefile.am (check-local): Move `$(TESTS_ENVIRONMENT)' and
        `$(BUILDCHECK_ENVIRONMENT)' to be arguments of `testsuite', so
        that reruns will remember it; set enviroment variable
        `CONFIG_SHELL' so the suite will know which shell it was started
        with.
        (installcheck-local): Likewise, for `$(TESTS_ENVIRONMENT)' and
        `$(INSTALLCHECK_ENVIRONMENT)'.
        * tests/testsuite.at (LT_AT_TAG): Do not set the compiler
        variable here.
