Recently in Buildroot the option BR2_PIC_PIE has been enabled by default along
with other hardening features [1]. Since then the nios2 defconfig
qemu_nios2_10m50_defconfig is failing to boot due to a segfault in init program:
Run /init as init process
with arguments:
/init
with environment:
HOME=/
TERM=linux
Failed to execute /init (error -12)
See Buildroot build log and Qemu runtime test log in build artifacts [2].
Analyzing one of the binary with strace show that the problem occur
very early when starting the new process:
# strace ./busybox
execve("./busybox", ["./busybox"], 0x7f91ce90 /* 10 vars */) = -1 ENOMEM
(Cannot allocate memory)
+++ killed by SIGSEGV +++
Several binutils/glibc/gcc version has been tested without any success.
The issue has been reported to the glibc mailing list but it can be a linker
or kernel bug [3].
For the Buildroot 2021.05 release, disable BR2_PIC_PIE until the problem is
found and fixed.

Due to the recent events at Frenode [0], the channel has become a bit
unreliable (much spammed), and users have started to move away already,
as quite a few other projects have moved their IRC presence away from
Freenode.
There are a few alternatives. The first to spring to mind, is the new
Libera.Chat network [1], managed by the previous Freenode staff, so we
could expect quite a good experience there. However, it is a very young
network. The second well known alternative is the long-established OFTC,
which has been very reliable in its 20 years of existence.
So, let's move to OFTC, just because it has a track-record of robustness
(which Libera.Chat still has to build, for being young).
Note: there are a lot of other IRC networks, some very good too, but we
probably would be much off-topic on most of them.

This reverts commit a8a147f604.
That commit incorrectly made use of BR2_TOOLCHAIN_SUPPORTS_PIE, when it
should have been using BR2_PIC_PIE.
Besides, another attempt is pending, that unconditionally disables it as
it will be set by the toolchain wrapper already.
For both reasons, revert rather than switch over to BR2_PIC_PIE.

- Kept FORTIFY level 2 option as the default is now level 1.
- Removed all SSP options as the default now uses the best
option based on toolchain support.
- Similar to SSP, for RELRO, the default now uses the best
option based on toolchain support.
