  dd58d666ac08eb5eb81e4956172fc52b3bf0ab38: selftests/nolibc: make sure gcc always use little endian on MIPS (2023-06-09 11:46:10 -0700)

----------------------------------------------------------------
nolibc updates for v6.5

o	Add stackprotector support.

o	Fix RISC-V load-store instruction syntax to support 32-bit
	binaries, plus fixes for generic 32-bit support.

o	Fix use of s390 sys_fork().

o	Add my_syscall6() for ARM.

o	Support different platforms having different errno definitions.

o	Fix ppoll/ppoll_time64 arguments (add the fifth argument).

o	Force use of little endian on MIPS.

o	Improved testing, for example, better handling of different
	compilers and compiler versions, comparing nolibc behavior
	to that of libc, and additional test cases.

o	Improve syntax and header ordering.

o	Use existing <linux/reboot.h> instead of redefining constants.

o	Add syscall().
