  configure: fix libtirpc pkg-config detection

The conditional tested whether the string "pkg-config libtirpc" is empty, which it never is, so the fallback block ran unconditionally. Use $PKG_CONFIG --exists as intended, and route the block's other pkg-config calls through $PKG_CONFIG too so a cross pkg-config is honored. Behavior is unchanged in practice: without libtirpc.pc the block is now skipped and configure fails later with the same explicit error. Refs #652.
