916730425594 ("elf: Add elf_backend_add_glibc_version_dependency")
introduced adding an extra GLIBC_2.36 version dependency for x86_64. But
on x86_64 GNU/Hurd, there has never been a glibc 2.36 port, and thus the
GLIBC_2.36 version is not defined. The additional version dependency is
thus spurious and produces binaries that cannot be executed:
./test: /lib/x86_64-gnu/libc.so.0.3: version `GLIBC_2.36' not found (required by ./test)
This change fixes this by adding the version dependency only on x86_64
Linux.
That is wrong. Your patch checks the
building system, which can be different
from the target.
