Is this an illegal processor instruction? Webkitgtk and gtk+-3 are being compiled for i486.

Are you specifying the architecture properly through the compiler flags, by setting CFLAGS/CXXFLAGS envs to appropriate values?

Thanks for the reply - things were configured as follows:

CFLAGS="-march=i486 -mtune=i686 -Os -pipe  -fno-exceptions -fno-rtti " CXXFLAGS="-march=i486 -mtune=i686 -Os -pipe " ./configure --prefix=/usr/local --enable-shared --libexecdir=/usr/lib/webkitgtk3 --enable-introspection --disable-geolocation --disable-webkit1 --enable-web-audio
