undefined LFS64 symbols on musl 1.2.4

[12101111]

Zig Version

0.10.1

Steps to Reproduce and Observed Behavior

musl 1.2.4 remove those symbols: https://git.musl-libc.org/cgit/musl/commit/?id=246f1c811448f37a44b41cd8df8d0ef9736d95f4

Expected Behavior

std should use symbols without 64 suffix on musl target

[LinuxUserGD]

Should be fixed by #16098

[ifreund]

musl 1.2.4 remove those symbols: https://git.musl-libc.org/cgit/musl/commit/?id=246f1c811448f37a44b41cd8df8d0ef9736d95f4

From that commit it looks like the workaround implemented in musl's dynamic linker does not work for zig since zig uses it's own lld copy to link on linux.

I also experienced a similar error using ziglang 0.11.0 (released today), where as rolling back to ziglang 0.10.1 then everything works again.

Below shows an example of the error that we experienced when we build a rust project via cargo-zigbuild.
