[PATCH v3 1/2] selftests/nolibc: remove the x32 testcase

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

From: Thomas Weißschuh <linux@weissschuh.net>

Support for the x32 ABI is about to be removed from the kernel itself.
This will break the nolibc x32 testcase.

Remove the testcase to avoid breaking the testsuite in general.

This also ends official support from nolibc proper for x32. But as there
is no clear x32-specific code in the nolibc codebase, there won't be a
removal patch for that.
