[PATCH 3/6] Andes nds32: libgcc of nds32 porting.

[Chung-Ju Wu <jasonwucj at gmail dot com>]

Hi,

This patch consists of libgcc parts for nds32 target.
We support two kinds of libgcc implementation: newlib and mculib,
controlled by --with-nds32-lib=[newlib|mculib] when configure gcc.
In newlib setting, we use default libgcc impelmentation provided
by gcc, and take soft-fp as our software floating point library.
As for mculib setting, many modules have been hand-coded with
assembly codes for code size consideration.

We also have dozens of assembly codes under the directory 'isr-library'
for creating libnds32_isr.a which is used for interrupt support
in nds32 target.
