  # HEAD: 0d8c461adbc4a43736927f93db69ae376efbc2f1: tools/nolibc: x86_64: add stackprotector support (2023-03-27 16:26:10 -0700)

----------------------------------------------------------------
nolibc updates for v6.4

o     Add support for loongarch.

o     Fix stack-protector issues.

o     Support additional integral types and signal-related macros.

o     Add support for stdin, stdout, and stderr.

o     Add getuid() and geteuid().

o     Allow S_I* macros to be overridden by program.

o     Defer to linux/fcntl.h and linux/stat.h to avoid duplicate
	definitions.

o     Many improvements to the self tests.
