Still not clear. The combination "glibc" and "qemu semihosting" doesn't make sense. The triplet "aarch64-none-elf" is a gcc thing and has no referent in qemu. Are you building qemu-system-aarch64 for x86_64-linux, using an old x86_64 sysroot? In any case, glibc 2.11.1 is definitely out of support. Even CentOS 6 used 2.12 and we don't support that anymore either. Of the current long-term-support distros, I believe the oldest version of glibc is CentOS 7 with 2.17. As recently mentioned in https://lists.gnu.org/archive/html/qemu-devel/2019-08/msg04514.html we may accept a small patch with a large comment, but there are no guarantees how long we will keep such workarounds. I encourage you to re-examine why you're carrying around a 10 year old glibc. r~
