fix: fix cross compile to ARM926EJ-S is Broken (closes #15281)

[CGQAQ]

arm926ej_s arch should be ARMv5TEJ according to wikipedia, and in our company, we have this chip, the readelf below shows what is the native executable attributes should be look like:

but when we use zig to crosscompile using zig cc -o x main.c --target=arm-linux-gnueabi -mcpu=arm926ej_s the result of readelf's Tag_CPU_arch is v5TE

I don't know this change is enough though, please let me know if I need change something else.

PS: i didn't test this myself because I cant compile zig_bootstrap due to ziglang/zig-bootstrap#148, this change is suggested by @nekopsykose in #15281 (comment)

closes #15281

This file is generated from LLVM data so if this fix is correct then LLVM has a bug in it. Ideally update_cpu_features.zig would override this feature but that doesn't seem possible currently.

The next step to solving this problem is, as @Vexu noted,

1. sending a patch to fix this upstream in LLVM and
2. updating tools/update_cpu_features.zig to augment LLVM's incorrect data (we already have several such augmentations)

@CGQAQ: Unless you are doing (2) from this list above, there is no need to update this branch; you can leave the PR alone and someone will take care of it eventually.

oh! thanks
