after selecting gcc11 and emerge glibc uname starts to hang every time its been used when i emerge a package . i dont have much to go on but i report any way.
It's a glibc bug: https://sourceware.org/PR26690. Should be fixed in next glibc release.
Created attachment 668477 [details, diff] glibc-9999-alias.patch Meanwhile you can use glibc-9999-alias.patch (or an upstream patch). You will need to drop it to /etc/portage/patches/sys-libs/glibc. It should be safe to kill hung uname processes while you are building glibc on a broken system. postage does not check exit status of it.
