Possible to update glibc version?

[mfreeborn]

I see that the current version of glibc in these toolchains is 2.27, however, my application required (at least) 2.30. Would it be possible to release a new batch of toolchains with updated libraries?

Another question... how would one go about customising the sysroot within the finished toolchain directory? I would like to add a few more libraries to sysroot, specifically I would like to build an up to date version of libcamera: https://libcamera.org/getting-started.html.
