Rollup merge of #100621 - taiki-e:armv4t-atomics-32, r=cuviper 
Pass +atomics-32 feature for {arm,thumb}v4t-none-eabi

Similar to 89582e8193, 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. (https://github.com/taiki-e/portable-atomic/pull/28#discussion_r946604136)

Closes #100619
