Hello,

The path of test-driver into the generated src/tests/Makefile used in parallel tests could end in an absolute or wrong path in some cases like:
- Build dir separated from source dir.
- ./configure run with absolute path

In automake-1.14.1/bin/automake.in $am_config_aux_dir is defined relative to $(top_srcdir). This variable is used in handle_per_suffix_test function to call test-driver in parallel-tests. $top_srcdir is not anymore a relative path and will end by calling test-driver from an absolute path of source directory.

In Yocto build directory was separated from source directory and package test framework run some tests at runtime on target. Having an absolute path for test-driver in Makefile could cause problems.

I propose for test-driver the path to be relative path and $top_builddir for now looks to guarantee this path. In this way the tests can be run at build time and runtime.
Please find attached proposed patch.
Could you share your view on this issue?

Thanks,
Adrian Calianu
