Pass +atomics-32 feature for {arm,thumb}v4t-none-eabi
Similar to rust-lang@89582e8, but for ARMv4t.
Pre-v6 ARM target does not have atomic CAS, except for Linux and Android where atomic CAS is provided by compiler-builtins. So, there is a similar issue as thumbv6m.
I have confirmed that enabling the `atomics-32` target feature fixes the problem in the project affected by this issue. (taiki-e/portable-atomic#28 (comment))
Closes rust-lang#100619
