configure: warn about excessive stack usage
Use a 120 KiB per-function threshold. This roughly matches the default
thread stack size on Musl, which is 128 KiB, leaving some headroom for
caller frames.
This warning draws attention to functions in the codebase that may have
excessively large stack frames. A few functions could benefit from
reducing their frame size.
120 KiB is a reasonable limit. If a function requires more stack, it
likely would benefit from restructuring the code.
