I'm not sure if your patch is correct.
glibc has the system of earliest symbol versions, and so on certain
architectures
GLIBC_2.3.4 symver will not appear at all.
Given:
./sysdeps/mach/hurd/shlib-versions:DEFAULT GLIBC_2.2.6
./sysdeps/unix/sysv/linux/csky/shlib-versions:DEFAULT
GLIBC_2.29
./sysdeps/unix/sysv/linux/microblaze/shlib-versions:DEFAULT
GLIBC_2.18
./sysdeps/unix/sysv/linux/arc/shlib-versions:DEFAULT GLIBC_2.32
./sysdeps/unix/sysv/linux/m68k/coldfire/shlib-versions:DEFAULT
GLIBC_2.4
./sysdeps/unix/sysv/linux/arm/shlib-versions:DEFAULT
GLIBC_2.4
./sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions:DEFAULT
GLIBC_2.2
./sysdeps/unix/sysv/linux/riscv/shlib-versions:DEFAULT GLIBC_2.27
./sysdeps/unix/sysv/linux/riscv/shlib-versions:DEFAULT GLIBC_2.27
./sysdeps/unix/sysv/linux/riscv/shlib-versions:DEFAULT GLIBC_2.33
./sysdeps/unix/sysv/linux/riscv/shlib-versions:DEFAULT GLIBC_2.33
./sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions:# DEFAULT
Earliest symbol set
./sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions:DEFAULT
GLIBC_2.16
./sysdeps/unix/sysv/linux/x86_64/64/shlib-versions:# DEFAULT
Earliest symbol set
./sysdeps/unix/sysv/linux/x86_64/64/shlib-versions:DEFAULT
GLIBC_2.2.5
./sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions:DEFAULT
GLIBC_2.17
./sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions:DEFAULT
GLIBC_2.3
./sysdeps/unix/sysv/linux/nios2/shlib-versions:DEFAULT
GLIBC_2.21
./sysdeps/unix/sysv/linux/aarch64/shlib-versions:DEFAULT
GLIBC_2.17
and the limited list of arches supported by libsanitizer, I'd say at least
riscv*, powerpc64le and aarch64 (and maybe x86-64 -mx32 if supported) are
affected.
