bug#19042: test-driver path in automake 1.14.1

[Adrian Calianu]

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
