FYI: Trying to build lang/rust 1.94.0 in an armv7 poudriere-devel jail running a non-debug main on aarch64: "fatal runtime error: out of TLS keys, aborting"

FYI:

# grep 'out of TLS keys, aborting' \
  /usr/local/poudriere/data/logs/bulk/\
main-armv7-default/2026-03-25_11h57m49s/logs/errors/rust-1.94.0.log \
| wc -l
       6

Reportedly, the rust code making the report looks something like:

if unsafe { libc::pthread_key_create(&mut key, mem::transmute(dtor)) }
!= 0 {
    rtabort!("out of TLS keys");
}


Note: The aarch64 poudriere-devel jail running a non-debug main built
lang/rust just fine on the same Microsoft Dev Kit 2023 (8 cores).

# poudriere jail -l

The environment was from an official pkgbase distribution installation
for both.
