fault-linux-i386.h is not suitable for your situation. The build should use
fault-linux-mips.h.

Most likely, in this build, you have not provided the correct --host option.

In the previous build you gave:
  ./configure --target=mips-openwrt-linux --host=mips-openwrt-linux 
--build=x86_64-pc-linux-gnu
Here the --target is not needed (since libsigsegv is not a compiler, there
is no notion of "target"), and --build is not needed (since it will be
autodetected anyway). The essential setting is --host=mips-openwrt-linux,
and this one IS NEEDED.
