This removes all compatibility code normally compiled into glibc for
kernel < 5.10 from our build. The build glibc version will only work
with Linux kernel >= 5.10.

dwarves is a set of tools that use the debugging information inserted in
ELF binaries by compilers such as GCC. Utilities in the dwarves suite
include pahole, which can be used to find alignment holes in structs and
classes, and also extracts other information such as CPU cacheline
alignment, helping pack those structures to achieve more cache hits.
These tools are also used to encode and read the BTF type information
format used with the bpf syscall, making this a Linux build dependency
when using kernel BTF information.

In addition it contains the following improvements:
* protect stack canary from leak via read-as-string by zeroing second byte
* fix excessively slow TLS performance on some mips models

Enable this option and thus re-include crypt() support for the SHA256,
SHA512 and Blowfish ciphers on all devices. According to commit
9365745f8e ("musl: add a hack to remove unused crypt() algorithms,
saves ~14k after lzma") it should add about ~14k to the resulting image,
which seems to be a reasonable size increase for consistent crypt()
support.
Decided to not remove this hack completely as it might be still useful
for people trying to fit custom images onto smaller devices and the
patch is rather simple so we can afford to keep it for now.

At configuration time, gcc assumes that ppc64be targets use the ELFv1
ABI, and ppc64le targets use the ELFv2 ABI. However, musl libc does not
support the ELFv1 ABI on ppc64 at all, regardless of the endianness.
Therefore, when building for a ppc64 arch and with musl libc, instruct
gcc to use the ELFv2 ABI.
