Subject: [PATCH nolibc 07/18] selftests/nolibc: add a few tests for some libc functions
Date: Wed, 31 Aug 2022 11:21:37 -0700

From: Willy Tarreau <w@1wt.eu>
The test series called "stdlib" covers some libc functions (string,
stdlib etc). By default they are automatically run after "syscall"
but may be requested in argument or in variable NOLIBC_TEST.
