commit 2753c6f3b86b9532ce2e0c580c59d0413b68e139
Author: Thomas Schwinge <tschwi...@baylibre.com>

Disable parallel testing for 'rust/compile/nr2/compile.exp' [PR119508]
..., using the standard idiom. This '*.exp' file doesn't adhere to the
parallel testing protocol as defined in 'gcc/testsuite/lib/gcc-defs.exp'.
This also restores proper behavior for '*.exp' files executing after (!)
this
one, which erroneously caused hundreds or even thousands of individual test
cases get duplicated vs. skipped, randomly, depending on the '-jN' level.
