gcc vector extension seems available for some years https://gcc.gnu.org/onlinedocs/gcc-3.3.4/gcc/Vector-Extensions.html
It also complied successfully for raspberry using linaro gcc toolchain. Perhaps kindle toolchain is special. If you cannot fix it then you may disable it in blis.h and let it fall through to c ref version. Performance will be more or less the same (no improvement) if there is no decent hardware simd support.
