Hi Caolan,

Libreoffice bridge code won't compile on new CPUs which add -mavx to cxxflags with 
--march=native.
As first idea for the fix is actual ban for the -mavx cxxflag by adding -nomavx.


I'm curious, in what way does the implicit -mavx cause the build to fail?


I wonder how far we'd get rebasing the bridges on on libffi ? There's a
fair bit of overlap.


Hard to say - I've re-used the libffi implementation of the small struct
handling in the x86-64 bridge, but did not go any further; might be
doable, but for sure not trivial :-)

Kendy
