I noticed that when testing glibc with a cross compiler I got

UNSUPPORTED: nptl/tst-thread_local1

because the libstdc++-v3 configuration for cross compiling defaulted
to __cxa_thread_atexit_impl not being available.  This patch fixes
GLIBCXX_CROSSCONFIG to run the same test (for the case covering
targets with glibc) for __cxa_thread_atexit_impl as for native
compilation, just as it runs most of the other tests done for native
compilation (for these targets, it's not possible to build libstdc++
without already having built libc, so link tests are OK).

Tested with no regressions for cross to arm-none-linux-gnueabi.

	* crossconfig.m4 (GLIBCXX_CROSSCONFIG) <*-linux* | *-uclinux* |
	*-gnu* | *-kfreebsd*-gnu | *-knetbsd*-gnu | *-cygwin*>: Check for
	__cxa_thread_atexit_impl.

As the PR points out, the "simple" reorder algorithm makes bigger code
than the STC algorithm did, for -Os, for x86.  I now tested it for many
different targets and it turns out to be worse everywhere.

This simple patch tunes "simple" a bit; this makes it better than STC
almost everywhere.  The only exceptions (for the targets where I have
results) are x86 and mn10300.  For those targets it may be best to switch
the default algorithm for -Os to STC.

This patch adds an easy way to write tests for expected multiline
output.  For example we can test carets and underlines for
a particular diagnostic with:

/* { dg-begin-multiline-output "" }
 typedef struct _GMutex GMutex;
                ^~~~~~~
   { dg-end-multiline-output "" } */

multiline.exp is used by prune.exp; hence we need to load it before
prune.exp via *load_gcc_lib* for the testsuites of the various
non-"gcc" support libraries (e.g. boehm-gc).
