Lower glibc version requirement

[xen0n]

2.38 should be enough for recent (2024) distros, mainly several Chinese-developed ones (think the openBlahBlah ones), but @sunhaiyong1978 pointed out in IM that openEuler 22.04 LTS has users and it's glibc 2.34 (!!).

It seems not so easy to make stripped-down openEuler sysroots though; see also https://gitee.com/openeuler/openeuler-docker-images/issues/I9CRB5.

Isn't the first Glibc release supporting LoongArch 2.36? If they must use a "pheasant" glibc version they should take care of .net on their own, IMO.

It's a glibc 2.34 but patched to glibc 2.36 ABI from LoongArch's perspective. So from our perspective we can just use a glibc 2.36 sysroot.

But the problem is that nowadays it can be hard to find a distro that simultaneously has glibc 2.36 and up-to-date everything else...

IIRC their qemu qcow2 is reasonably stripped down, I built an rootfs out of 24.03 qcow2 for the 2K0300 99pi board once.
