[2.24] fix MIPS static executable segfault

Previous commit f25603579c0a04b3d5099259cf54c5b3c8775b78
isn't complete because .ctors/.dtors in crtbegin*/crtend*
aren't excluded from .init_array/.fini_array.  Static
executable (eg. $NDK/tests/device/static-executable) causes
"Bus Error" because call_array() in __libc_init() call ffffffff
from __INIT_ARRAY__ not properly terminaed by NULL.

    Disassembly of section .init_array:

    000b42ac <__INIT_ARRAY__>:
    b42ac:	ff ff ff ff

    000b42b0 <__CTOR_LIST__>:
       b42b0:	ff ff ff ff dc 09 08 00 f8 09 08 00 00 00 00 00

    000b42c0 <__CTOR_END__>:
       b42c0:	00 00 00 00

Note that Android uses .init/.fini_array (move away from .ctors/.dtors),
but we can't simply remove _CTOR* from crtbegin_static/dynamic.o
because older device (eg. ICS) call_array() on CTOR_LIST

The correct fix is to exclude them

Thanks to icebergfu@gmail.com for identifying the issues.
