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-lang/rust
note: backtrace dumped due to SIGSEGV! resuming signal
error: could not compile `p384` (lib)
WARNING: Backtrace (BB generated script):
#1: oe_cargo_build,
/home/poky/build/tmp/work/core2-32-wrs-linux/cargo/1.79.0/temp/run.do_compile.3262358,
line 193

line 206
Setting RUST_MIN_STACK to 8MB conditionally for DEBUG builds only handles
the stack overflow and SIGSEGV.
