nds32: add support for new architecture
Add support for Andes Technology NDS32 architecture.
See here http://www.andestech.com/en/index/index.htm for more
informaton. Verification of the port from an older uClibc
port was done on a sponsored AG101p board.
The testsuite only has 5 errors, three are related to
an existing bug in dlclose() with LT.old, also happening
on cris32 and m68k.
Failures to fallocate/posix_fallocate are unresolved.
Thanks to Andes Technology sponsoring the hardware and
being very helpful while doing the uClibc-ng porting.
