patch to fix features/archives test 10 on sunos

[Dmitry Goncharov]

Good morning.

ar add output is system dependent.
This makes features/archives test 10 fail on sunos.
This patch uses the output of `ar rv` rather than a hardcoded string.

linux
$ ar rv libxx.a 1234567890123456b
a - 1234567890123456b

sunos
$ ar rv libxx.a 1234567890123456b
a - 1234567890123456b
ar: writing libxx.a
