compiler-rt: Build clang_rt.profile library when possible

To enable clang_rt.profile library do something like the following in
local.conf or your distro configuration.

    PACKAGECONFIG:pn-compiler-rt = "profile"

The clang_rt.profile library is used to collect coverage information. It is a
static library, so does not introduce any additional footprint in
target images.
