Invalid MEX file - Buffer

[Guillaume Flandin]

Dear Peri,

if you follow the same instructions than there and recompile, it should
get you sorted:
http://en.wikibooks.org/wiki/SPM/Installation_on_64bit_Linux#Other_problems_with_lstdc.2B.2B
(basically, remove all reference to -lstdc++ in mexopts.sh).

Best regards,
Guillaume.
