FWIW, I ran into this issue as well the first time I tried building webkitgtk with a compiler tuned for armv7a. I did not try many variations but was able to build with a machine configuration with DEFAULTTUNE set to armv7ahf-neon (hard float with neon simd). This link seems to also provide some more information on what configurations can be used to build webkitgtk on arm:     http://patchwork.openembedded.org/patch/105081/ Cheers,     -Tristan
