COVER: glibc port for 32-bit RISC-V (RV32)
This patch set contains the glibc port for 32-bit RISC-V.
This is based on the original work from Zong Li [1] and has been
updated to use a 64-bit time_t.
This requires a 5.4+ kernel and all of the testing has been done using
the 5.4 stable kernel.
Nothing fails when running ./scripts/build-many-glibcs.py (for all
targets) on my x86-64 machine.
This is the current list of tests that fail when running inside QEMU RV32
system emulation on the 5.4 kernel:
FAIL: elf/tst-ldconfig-ld_so_conf-update
FAIL: io/tst-lockf
FAIL: misc/test-errno-linux
FAIL: nss/tst-nss-files-hosts-long
FAIL: resolv/tst-resolv-res_init-thread
FAIL: stdio-common/bug22
FAIL: stdlib/tst-strfrom
FAIL: stdlib/tst-strfrom-locale
FAIL: sysvipc/test-sysvmsg

This specific version can be found here: https://github.com/alistair23/glibc/tree/alistair/rv32.1
---Changelog---
v1:
- Update based from feedback on RFCv6
- Improve test passing
- There are only 9 tests failing now
- Rebase on Lukasz's work
- Send only the RV32 specific patches (other patches are already merged
or on the list)
RFC v6:
- Rebase on top of accetpted patches
- Fix issues so that the tests actually run
RFC v5:
- Hopefully finally get the correct layout for the *64 syscalls
- Sort out the Changelog
RFC v4:
- Continue to fix things that weren't working
- Update the coding style to match glibc
- Update the __ASSUME_TIME64_SYSCALLS work to better match Lukasz's
work
RFC v3:
- Remove all "Hack" patches
- Incorporate upstream comments
- Ensure we don't break RV64
- Lot's more testing and fixes
RFC v2:
- Add Lukasz's patches
- Update the non HACK syscalls after feedback
- define __ASSUME_TIME64_SYSCALLS and __ASSUME_RLIM64_SYSCALLS
- Remove lockf64.c
- Other smaller changes from RFC v1
