[PATCH v5 00/11] nds32 glibc port, v5

[Vincent Chen <vincentc at andestech dot com>]

This is the fifth version of the nds32 port. In order for nds32 port
to catch up the glibc 2.30 release, we removed the hard-fp support from
the nds32 port because the outdated soft-fp module in the kernel caused 21
glibc test cases to fail. All CPU-relative information can be found from
<http://www.andestech.com/en/products-solutions/product-documentation/>.
The ISA and ABI used in nds32 ports are documented in the "AndeStar ISA Manual"
and "Andes Programming Guide for ISA V3", respectively.

The patchest has been cross-tested on the FPGA board based on Linux 5.0
and glibc commit 119269606996. In addition to the known
architecture-independent issues on the per-release wiki pages, there are two
unexpected FAIL cases, libio/tst-wfile-sync and misc/tst-syscall-list,
The reasons for their failure are as follows.

1. libio/tst-wfile-sync
In the testcase, an unexpected Error code -ESPIPE retunred by the function
xlseek() causes this testcase to fail. This is an architecture independent
issue and I has reported it to Bugzilla (Bug 24668).

2. misc/tst-syscall-list
The reason for the failure is that udftrap is missing from syscall-names.list.
This syscall only exists in Linux 5.0 and 5.1 and will be renamed to
fp_udfiex_ctrl in Linux 5.2. Should I send a patch which adds udftrap
into syscall-names.list, and resend a patch for renaming after the default
kernel version in build-many-glibcs.py is changed to 5.2? or I only send one
patch which adds fp_udfiex_ctrl to syscall-names.list and note this failed case
as a known issue?
