Add FreeBSD 9 support to libcxxabi testing framework

[emaste]

test/lit.cfg

204

Use sys.platform.startswith('freebsd') instead, so that we don't get "unrecognized system" on FreeBSD 10.

See http://bugs.python.org/issue12326 and http://bugs.python.org/issue12795 for the sad details :(

What was this patch generated against? It seems to be against a old and very customized version of lit.cfg.
Please generate the diff against the master. I'm very interested in seeing this patch in master ASAP. However the patch you submitted will not work unless you submit the rest of your changes as well.

Some points:

• We still need to handle the cxxrt ABI.
• llvm_unwinder is not set anywhere (in master) but I'm very interested to see it supported.
• Please add freebsd to the locales table (in master). Here is the change I made to get it working:

'FreeBSD' : {
        'en_US.UTF-8': 'en_US.UTF-8',
        'cs_CZ.ISO8859-2': 'cs_CZ.ISO8859-2',
        'fr_FR.UTF-8': 'fr_FR.UTF-8',
        'fr_CA.ISO8859-1': 'fr_CA.ISO8859-1',
        'ru_RU.UTF-8': 'ru_RU.UTF-8',
        'zh_CN.UTF-8': 'zh_CN.UTF-8',
    },

Thanks for working on this.

I'm a massive colossal idiot. Please ignore everything I just said. I read this as libcxx not libcxxabi. I'm very sorry.

This patch is obsolete. libcxxabi's test env was updated to match libcxx's months ago.

You can abandon the patch so that it gets removed from outstanding lists.
