Subject: [PATCH 09/10] Prevent running check tests on host if cross compiling

This patch enables running the 'make check' tests on the target
in a cross-compiled environment. If not cross-compiling, then 'make
 check' builds and executes the tests; no change from this patch.
In a cross-compiling environment, the make variable CROSS_COMPILE is
set which bypasses assiging tests to the makekfile variable TESTS.
Since TESTS is empty, the 'make check' process never tries to run the
tests on the hosts.  On the target, the tests must be run manually.

Also, in the libutil++ tests, a makefile variable SRCDIR is passed into
the compilation phase, pointing to the runtime location of the test
'file-manip-tests'.  The mechanism used for a host test, based on
'topdir' doesn't work.  Instead, if CROSS_COMPILE is set, the
makefile takes the path of SRCDIR from the build environment and not
from an expression based on the host path 'topdir'.
