  avx2 configure: Disable if static build

This avoids a segfault like the following for at least some 4.8 versions
of gcc when configured with --static if avx2 instructions are also
enabled:

        Program received signal SIGSEGV, Segmentation fault.
        buffer_find_nonzero_offset_ifunc () at ./util/cutils.c:333
        333     {
        (gdb) bt
        #0  buffer_find_nonzero_offset_ifunc () at ./util/cutils.c:333
        #1  0x0000000000939c58 in __libc_start_main ()
        #2  0x0000000000419337 in _start ()
