LoongArch: ldconfig: Ignore EF_LARCH_OBJABI_V1 in shared objects
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.
