Strip debug symbols from test binaries using RUSTFLAGS='-C strip=debuginfo'
to reduce binary sizes from 300+ MB to ~140 MB.

This is especially critical for PowerPC mac99 which has a hardcoded 768MB
RAM limit in QEMU. Without stripping, test binaries uploaded to /tmp (tmpfs)
cause 'No space left on device' errors during test execution.

The size reduction also benefits all other architectures by reducing
memory pressure and upload times during testing.
