This reverts commit 8084ea55b7.

As we've updated SDK in upstream CI we can revert this

I spent several hours debugging a weird stack pointer corruption bug and
discovered that QEMU appears to mess up register contents when an interrupt
fires during the execution of a branch with a delay slot.
Instead of trying to fix qemu, let's just tell the compiler to not generate
code that uses the branch instructions with delay slots.
Closes: #60071
