glibc: Disable CPU ISA level requirement check

We experience the following error and fail to boot on qemu64 machine

/lib64/libc.so.6: CPU ISA level is lower than required
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00

As stated in [1],

Passing -march= causes glibc to add annotations not compatible to run
result on -march= as too high ISA level is inferred.

ISA level is a new feature of 2.33 release.

Until it's fixed let's disable ISA level inference with
    libc_cv_include_x86_isa_level=no
(no better configure option yet).
