Subject: [PATCH] add execveat syscall wrapper
The execveat syscall was added to Linux in v4.0 (released in 2015),
and the libc wrapper function was added to glibc in 2021
The AT_EXECVEAT_CHECK option was added to Linux 6.14, so I believe the
syscall has the potential to become more widely used. Thus it is
important for musl to provide the wrapper.
