gcc flag -m64 is not handled in cmake-ide--filter-ac-flags

Compiling my project with gcc, but editing in emacs with auto-complete clang requires a work around. When I hit auto-complete I get:
clang failed with error 1:

Invoking the above command on the terminal I get:
error: unknown argument: '-m64'
error: unknown argument: '-m64'
error: unknown argument: '-m64'
The fix is simple, just update the flags in cmake-ide--filter-ac-flags:
(defun cmake-ide--filter-ac-flags (flags)
"Filter unwanted compiler arguments out from FLAGS."
(cmake-ide--filter
(lambda (x)
(cl-loop for flag in '("-m32" "-m64" "-Werror" "-c" "-fPIC" "-pipe" "-g" "-ggdb")
never (string-match (format "^%s$" flag) x)))
flags))
This fix seems a bit trivial to open a pull requst, but thought I'd let you know as it breaks the almost perfect automagic of cmake-ide. Thanks for developing this, one of my favourite emacs packages!
There's no such thing as too trivial for a PR ;)
Submit and I'll merge.
