2.8.1

1.The ptest run-builtins of bash fail, because the script:

        (exec -l -a specialname {THIS_SH} -c 'echo $0')
in the builtins.tests, it has option "-l", as the bash source
code shell.c said when a shell run startup file if:
	argv[0][0] == '-'

it is a login shell, it would read the file /etc/profile. The file /etc/profile contain the following:
if [ -x /usr/bin/resize ];then
/usr/bin/resize >/dev/null
fi
The above codes that was added by Ting Liu whose commit is

	73c481d2cbc3e7c7ef9f594126aec581ec75b689

It run the command /usr/bin/resize which is produced by busybox, in the busybox source code resize.c, when you invoke it, it would output an escape sequence "^[7^[[r^[[999;999H^[[6n" to the stderr. So in the run-builtins scripts, it output a temp file /tmp/xx:

	${THIS_SH} ./builtins.tests > /tmp/xx 2>&1
the file /tmp/xx contain the above escape sequence, in the next step
we diff the /tmp/xx and builtins.right:
	diff /tmp/xx builtins.right && rm-f /tmp/xx
the run-builtins test fail. Because the escape sequence was output to
the stderr, so we need to filter the escape sequence to /dev/null to
solve the problem:
	(exec -l -a specialname {THIS_SH} -c 'echo $0') 2> /dev/null

in the file builtins.tests.

2.In the file tests/source5.sub, it contain:

	LC_ALL=en_US.UTF-8

So when we run the run-builtins test,we should ensure the system include the locales "en_US.UTF-8", such as we add the following to the local.conf:
IMAGE_LINGUAS_append = " en-us"
