For some Rust crates, like building p384 in DEBUG mode, a SIGSEGV
is encountered as follows:

     note: rustc unexpectedly overflowed its stack! this is a bug
     note: maximum backtrace depth reached, frames may have been lost
     note: we would appreciate a report at https://github.com/rust-l=

     note: backtrace dumped due to SIGSEGV! resuming signal
     error: could not compile `p384` (lib)

Setting RUST_MIN_STACK to 8MB conditionally for DEBUG builds only handles
the stack overflow and SIGSEGV.

s/to 8MB/from 2MB to 8MB/

Best to explain what the current default value in your commit log in case the rust devs increase the limit some day.

Is there an issue open for the p384 crate to reconsider their stack abuse?

If so, please include that link. If not, create one and link that.
