check if dtrace accepts -xnolibs and use it if available
dtrace without -xnolibs fails in a FreeBSD jail, so supply it
if possible

(perl #130108) separate compiled objects from dtrace modified objects
When generating an object file with "dtrace -G", dtrace also modifies
the input object files.
This causes two problems:
1) Since the objects are modified, their modification times are updated
which may break dependency checks by make.
2) on FreeBSD at least, once the object has been processed it can't be
processed again by dtrace -G

add elf to libswanted on FreeBSD 10.x
usedtrace builds add references to libelf symbols, causing link
failures without it.
at hints time we don't know if the user will interactively select
dtrace and there's no CBU, so it's added unconditionally on 10.x

(perl #130108) generate a dummy dtrace_main.o if perlmain.o doesn't contain
probes
efc4bddfd4 added generating a probes object file for perlmain.o, since
the compiler was generating probes even for unused inline functions.
The default compiler on FreeBSD 11 however doesn't generate probes for
these unused inline functions, and dtrace -G fails because it can't
find any.
So if dtrace fails for perlmain.o generate a dummy object file to
take its place.
Similarly for XS::APItest.
