Today i took some time to hack gcov/lcov with LTP.
I sent patches
- copy gcov supported files
- runltp with gcov enable
These patches more about hack but they work on standalone machine and
installing binaries in side the ltp tree.
people interested in test coverage could try these patches and see how it
looks like.
However, these patches can not be in mainline and these are not optimal
patches.
Sample LTP test coverage report is present here

I agree with you. there are many problems.

These are the default path to install.
/opt/ltp/bin/
/opt/ltp/testcases/bin/

These are the well known issues.
but looking forward to have a configurable parameter to travel each
directory and running testcases and generating gcov reports. However
supporting tools can be installed under ltp/bin/. gcov expects
source/binary/gcno/gcda to be present in the same location to generate
.c.gcov file .If wider developers/testers have same interest could work
running gcov/lcov on LTP source.
