perf tools: Fix perf builds with clang support
[ Upstream commit c2fb54a183cfe77c6fdc9d71e2d5299c1c302a6e ]
For libclang, some distro packages provide static libraries (.a) while
some provide shared libraries (.so). Currently, perf code can only be
linked with static libraries. This makes perf build possible for both
cases.
