built with GTK

I'm forwarding this to the people who are responsible for this.

In PR ports/72014 it was reported a long time ago that eclipse/gtk
crashes and this was tracked down to non-standard compiler optimizations
when building gtk. There have been similar bug reports filed against the
eclipse and gcc bug databases. Some gcc people have tracked it down to
incorrect stack alignment (see ports/72014 for the pointers) and have
received reports that using -mno-sse2 fixed it. Daniel has verified that
this seems to help our case also.
Therefore the question is, should we force -mno-sse2 to the compiler
flags for the gtk ports? I would expect less bug reports from people who
compile gtk apps with non-standard CFLAGS, at least.
