handle libc implementations which do not provide `error.h`
Introduce a configure time check for the presence of `error.h`. In the
case that `error.h` is not available, we can fall back to `err.h`.
Although `err.h` is not a C standard header (it is a BSD extension),
many libc implementations provide. If there are targets which do not
provide an implementation of `err.h`, it would be possible to further
extend the implementation to be more portable.
This resolves bug #21008.

lib: avoid potential problems with `-fno-common`
This properly homes the fallback function into a translation unit rather
than trying to define an inline common definition for the fallback path.
The intent of the original approach was to actually simply avoid adding
a new source file that is used for the fallback path. However, that may
cause trouble with multiple definitions if the symbol does not get vague
linkage (which itself is not particularly great). This simplifies the
behaviour at the cost of an extra inode.

Add lib/error.c
This new file was supposed to be part of 4d6dd0e5a "lib: avoid potential
problems with `-fno-common`".
