[libc] are compiler flags being cached?

[nickdesaulniers]

So in #87837, I'm trying to fix the failing setjmp/longjmp tests, but curiously none of the post submit bots have failed...

I wonder if the compiler flags are being cached in the cmake build? IIRC, there was something in cmake syntax where you could say set(foo value CACHE OFF) or something to stop that. Perhaps that (or whatever it is that I'm thinking of, or something else) is needed here?
