Mystery solved; zero FAILs again with mainline on freebsd5

[Loren James Rittle <rittle at latour dot waar dot labs dot mot dot com>]

At the end of last week, I finally solved the mystery of the last two
library FAILs (only crashed with -pthread) with mainline on freebsd5.
It appears that the thread library on FreeBSD5 allocates smaller
stacks (or better protected stacks) than FreeBSD4.  As committed since
location of memory allocation is not at issue in these tests. - Loren

	* testsuite/27_io/basic_istream/getline/wchar_t/5.cc: Make buf static.
	* testsuite/27_io/basic_stringbuf/setbuf/wchar_t/4.cc: Make ref and
	src static.
