No, it's not, but it's good you mention it.  Libtool would need a
similar change.

Change the
  AC_CHECK_LIB(dl, dlopen)

in gawk's configure.ac to be
  AC_SEARCH_LIBS([dlopen], [dl zrldsrl])

Autoconf doesn't have a native (specialized) check for dlopen, but
Libtool does.  But I do wonder whether dlopen has the same semantics
on Tandem.

If you would like to help port Libtool to Tandem (there seems to have
been at least some porting effort a long time ago), be encouraged to
grab a nightly tarball and try to build and run its testsuite there.
