LoongArch: ldconfig: Ignore EF_LARCH_OBJABI_V1 in shared objects

Browse Source 
Binutils 2.40 sets EF_LARCH_OBJABI_V1 for shared objects:

    $ ld --version | head -n1
    GNU ld (GNU Binutils) 2.40
    $ echo 'int dummy;' > dummy.c
    $ cc dummy.c -shared
    $ readelf -h a.out | grep Flags
    Flags:                             0x43, DOUBLE-FLOAT, OBJ-v1

We need to ignore it in ldconfig or ldconfig will consider all shared
objects linked by Binutils 2.40 "unsupported".  Maybe we should stop
setting EF_LARCH_OBJABI_V1 for shared objects, but Binutils 2.40 is
already released and we cannot change it.
