perf tools: Fix perf builds with clang support
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. Signed-off-by: Sandipan Das <sandipan@linux.vnet.ibm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com> Fixes: d58ac0bf8d1e ("perf build: Add clang and llvm compile and linking support") Link: http://lkml.kernel.org/r/20180404180419.19056-1-sandipan@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
