cwrapper fixes during freeze

[Jonathan Perkin <jperkin%joyent.com@localhost>]

Hi,

I'd like to commit the small changes below.  They fix a number of
issues seen in SunOS bulk builds (gfortran calls not going via the
wrappers and '-mt' being transformed to the invalid '-threads'), are
confined to USE_CWRAPPERS=yes which is not currently the default, and
should cause no regressions.

However they do touch mk/ and pkgtools/ during the freeze, so I'd like
approval and a sanity check prior to doing so.

Thanks!
