Add necessary c++ flags and link libraries to support builtin clang and
LLVM. Add all llvm and clang libraries, so don't need to worry about
clang changes its libraries setting. However, linking perf would take
much longer than usual.

Compile jvmti agent as part of the perf build. The agent library is
called libperf-jvmti.so and is installed in default place together with
other files:
$ make libperf-jvmti.so
BUILD: Doing 'make -j4' parallel build
...
CC jvmti/libjvmti.o
CC jvmti/jvmti_agent.o
LD jvmti/jvmti-in.o
LINK libperf-jvmti.so
$ make DESTDIR=/tmp/krava/ install-bin
...
$ find /tmp/krava/ | grep libperf
/tmp/krava/lib64/libperf-jvmti.so
/tmp/krava/lib64/libperf-gtk.so

This patch modifies the build dependencies on the jitdump support in
perf. As it stands jitdump was wrongfully made dependent 100% on using
DWARF. However, the dwarf dependency, only exist if generating the
source line table in genelf_debug.c. The rest of the support does not
need DWARF.
This patch removes the dependency on DWARF for the entire jitdump
support. It keeps it only for the genelf_debug.c support.

Fixes: e12b202f8f ("perf jitdump: Build only on supported archs")
[ Make it build only if NO_LIBELF isn't defined, as jitdump.o will only be built in that case ]

The __get_cpuid() test is only valid when compiling for x86. When
compiling for other architectures like ARM/ARM64 the test fails event if
the functionality is not required.
This patch isolate the build-in feature check to x86 platform, allowing
the compilation and usage of PMUs that use the AUXTRACE infrastructure
on other architectures (i.e ARM CoreSight).

There's no reason to keep it in separate directory now when we moved out
the rest of the files.
