lib/replace: let DISABLE_OPATH also undef __NR_openat2

2022-08-15T15:03:37+00:00

The reason for DISABLE_OPATH is to simulate a non-linux
system, so we should not use openat2() either.

lib/replace: add fallback defines for __NR_openat2

2022-08-15T15:03:37+00:00

sys/syscall.h might be older than the runtime kernel.

If the kernel has support for openat2() we should
try to use if anyway.

The callers have to deal with ENOSYS anyway,
so there's no difference if we get that from syscall(__NR_openat2)
or directly from rep_openat2().

lib/replace: use syscall(__NR_openat2) if available

2022-08-15T15:03:37+00:00

There's no glibc wrapper for openat2() yet, so we need
to use syscall(__NR_openat2) ourself.

replace: Add check for variable program_invocation_short_name

2018-11-13T10:11:11+00:00

It appears that wafsamba's configure() defines _GNU_SOURCE
unconditionally, so checking _GNU_SOURCE isn't enough to know if this
variable is available.

For example, it isn't available on AIX with the xlc compiler:

  [ 6/10] Compiling lib/replace/replace.c
  ...
  "../../lib/replace/replace.c", line 991.16: 1506-045 (S) Undeclared identifier program_invocation_short_name.

Instead, add a configure check for program_invocation_short_name and
use it.
