[PATCH v2 1/9] nds32: lib: To use generic lib instead of libgcc to prevent the symbol undefined issue.

[Greentime Hu]

We can use the generic lib to fix these error because the symbol of
libgcc in toolchain is not exported.

ERROR: "__ucmpdi2" [fs/xfs/xfs.ko] undefined!
ERROR: "__ashrdi3" [fs/xfs/xfs.ko] undefined!
ERROR: "__lshrdi3" [fs/xfs/xfs.ko] undefined!
ERROR: "__ashldi3" [fs/ntfs/ntfs.ko] undefined!
...
