[LTP] [PATCH 1/3] open_posix_testsuite/generate-makefiles.sh: Avoid inconsistencies with make version

[Richard Purdie]

With make 4.1, INSTALL_TARGETS+=<tab> will add a space to the variable whereas
with make 4.3, it will not. This leads to differing run.sh files in installed
in packages which is undesireable. If tests is empty we don't have to add
the line to the makefiles at all which seems like the easiest way to
avoid the differences in make behaviour.
