'bazel coverage' fails for C/C++ targets

[ljessendk]

It seems that the toolchain doesn't support building C/C++ targets with coverage.

Steps to reproduce:

1. cd examples/rules_cc
2. bazel coverage ...

Output:

ld.lld: error: undefined symbol: llvm_gcda_start_file
>>> referenced by hello_world.cc
>>>               bazel-out/k8-fastbuild/bin/_objs/hello_world/hello_world.o:(__llvm_gcov_writeout)

bazel 7.3.1
