Since 8534063 (configure: use pkg-config to find libtirpc), we use
pkg-config to check for libtirpc (he!).

As reported on the list, some user do not have the libtirpc registered
with pkg-config (even though it has been since at least 0.1.8).

So, partially restore the old checking code, as it was before 8534063,
but adapted to work with the pkg-config check, and also adapted to only
use proper macros (AS_IF) instead of shell constructs.

Re-introduce that old code in a separate function, so it is easy to get
rid of when we only want to support pkg-config in the future (i.e. when
virtually all libtirpc versions in the wild have been properly
installed).
