Autoconf includes the 'autotest' language, which parses a new file
tests.at to build up a (shell script) testsuite; as well as
documentation for a couple of hooks to add in configure.ac and your
Makefile to run such a testsuite. Such tests need not be C programs -
they are anything that you can drive via shell snippets. In fact,
autoconf's own testsuite is written in the autotest language. But I'm
not sure if this is what you had in mind.

Meanwhile, Automake has support for building up a testsuite based on
various input files, maybe it's easier to use?

AC_TRY_RUN is for determining a platform characteristic at configure
time, not for running a testsuite at make time. I think you're
confusing the issue, and don't need AC_TRY_RUN for a make-time test.
Also, AC_TRY_RUN is an obsolete wrapper around the newer AC_RUN_IFELSE
macro; this macro does not inherently require a C compiler, but runs a
configure-time compile/run/cross-compile-guess based on the current
language being probed in the configure.ac file (which is usually C, but
can be Fortran).
Furthermore, if your Makefile already knows how to run your tests, then
your Makefile.in (if you only use autoconf) or Makefile.am (if you also
use automake) can preserve those test rules as-is, and still run those
tests as you have always done as part of make.
